Hi,
I have a DELL Inspiron 15-3567, spec - i5 7th gen, 4GB ram, 512 GB HDD. But it is super slow and I can't even perform normal tasks like surfing the web or watching videos.
How can I improve this? Any help is appreciated.
An absolute low-end device, IMO.
1st thing of all things you could do is to disable all services you don't need. Normal Windows user can safely disable a dozens servives. You may look inside here
20 Unnecessary Background Services to Disable on Windows 10
A carefully handpicked list of unnecessary background services one can easily disable on a Windows 10 PC without affecting its performance and stability.

how to achieve this.
Thank you for the information, it will be really helpful.

1.Speed : phone is lightning fast with 624mhz CPU, nothing beats it, even while multi tasking it doesnt lag. movies play very smooth and audio/video are in sync.
2.Stable : with latest firmware phone is very stable, no freezing or lagging or running low on memory, no need to reboot it daily, this baby just keeps going at full speed.
3.Design : what a great design, samsung did a really good job at designing this phone, from the keyboard to the shortcut keys, the mouse / D-pad, even the menu's and custom layout inside windows. this phone is very user friendly, or atleast more than any other PPC device i have seen.
4.Connectivity : Signal strenght is great, it shines above the tytn 2 with signal quality, Hsdpa is fast and you will quickly get full speed downloading.
5.Customisable : with its odd 320x320 screen you'd expect to have lot of problems with 3rd party applications, yet there are hundreds of programs around that lets you customise almost anything on this device, which makes it one of the most flexible devices on the market.
6.Slim and light : phone is really light in weight and with its slim design fits easily in your pocket, yet it has a 624mhz cpu, 256 rom, 128 ram, 3g/Hsdpa, 2mp camera etc ... makes this device ultra portable with state of the art features.
7.Video calling : that actualy work right out of the box, i couldnt belive my eyes when i tried it and my brother popped up on the screen.... need i say more ?
8.Support : everywhere on the net you find I780 threads where people are very helpfull, this phone has great support and alot of followers.
9.battery : 2 Batteries !! when was it the last time you purchase a phone and get two batteries ? Satisfactory battery consumption (even with Bluetooth & 3G always on the drain rate is quite conservative)
10. User friendliness : for a PPC this phone is very user friendly, granted that it may take some a little longer to navigate around than others, compared to other ppc's this one is a walk in the park at finding what you want. samsung did a stunning job at making this phone ideal for both beginner and power user.
Well sadly i don't have an answer for that question yet...
I'm trying to think of a way to put KSM to the test on my android device.
As far as i understand it is possible that the kernel actually causes high CPU usage trying to map and unmap memory pages over and over again.
This issue is known for linux and other virtual machines so it is possible that the Same effect will be on the android vm
Testings that i found are not relevant to android.
For example:
The result is a dramatic decrease in memory usage in virtualization environments. In a virtualization server, Red Hat found that thanks to KSM, KVM can run as many as 52 Windows XP VMs with 1 GB of RAM each on a server with just 16 GB of RAM. Because KSM works transparently to userspace apps, it can be adopted very easily, and provides huge memory savings for free to current production systems. It was originally developed for use with KVM, but it can be also used with any other virtualization system - or even in non virtualization workloads, for example applications that for some reason have several processes using lots of memory that could be shared.

What i would really want to know is what would happen if each of these VMs Would run a different application/game/audio/graphics software at the same time ? or what if the same vm will run many different apps ? and also to compare cpu usage with and without KSM
Guess i'll need a tool for that. something like 'iostat' but for memory diagnostic and another tool to see a per process CPU usage but 'top' is not good enough for that.
Any way, the best test should present clear results with precised data.
I'll keep looking for legit way to put it to the test.
If you can think of a way to test KSM with android, please let me know.
This is a technique that relates mostly to processes like virtualisation. For example, when you load 5 windows XP VMs, you'll have a good 10 - 20 services that are practically the same in memory in each VM. Instead of each service using 10mb (ie, 10mb x 5 = 50mb), you only need say 15 or 20mb using KSM. If you use different applications, it is very unlikely that anything would be saved FOR THAT APPLICATION. However, the main elements of a Windows XP System would still be there (drivers, explorer, firewall, logon, search and so on). Means little in one setup, but when you have several VMs it is shown to be a huge advantage. As we know a simple XP install can use 500mb of RAM actively, and this is fairly uniform across instals.
With android, i don't know if there are specific RAM savings to be had. Don't know enough about the inner workings and the sandbox android puts its apps in or how apps interact with system services. Sadly, i can't think of a good way to test it out either, but i'll be keeping an eye on this topic for someone (much) more knowledgeable to come along.

KSM does not improve performance on Android just like that - all enabling KSM does, is enable SUPPORT for the Feature but Applications would have to make use of the feature, which they don't.
You can easily verify this like that :
echo 1 > /sys/kernel/mm/ksm/run
<wait and/or run the Applications of your choice>
cat /sys/kernel/mm/ksm/pages_sharing
IF the above shows a value > 0 then you are making use of KSM else it's just available, without anyone using the feature.
Here's an interesting Article that gives a little more insight :
http://www.linux-kvm.com/content/using-ksm-kernel-samepage-merging-kvm
By the way, the same is true for ZCACHE. If you really want to make better use of your Memory (RAM) then using ZRAM as a Swapdevice does work (and may often make sense, too).
That all said : There appear to be efforts to make use of KSM http://forum.xda-developers.com/showthread.php?t=1464758 - so things may well change ...
any update on this...?
Hi
Before I mean that applications and tweaks that will give them are the ones I've used, tested and have worked for me, so if you have that you know could be so kind as to comment as you lack have managed to control the use of RAM.
I also want to say sorry if my English is bad, I had to use the Google translator on the one hand and on the other my little knowledge in English, I'm sorry.
Not if you have noticed but in the Custom Roms of our device we overuse of RAM, this becomes more noticeable even Roms based on Lollipop, as can be CyanogenMod 12 where we can see that sometimes bubbles Messenger chat can be closed or the music is turned off, so I write this guide to explain how to control this use with some applications that truth to me I have worked.
-Apps:
The truth use applications to control the use of RAM is very embarrassing, since we are no longer in a device with 180MB of RAM, and have to use Tweaks or applications that optimize this, for some use some Tweak or application on this device is something good to optimize it a bit more, but we think 1GB of RAM and a 1.2 Ghz processor with 4 core.
To control the use of RAM I recommend...
Root Booster(FULL VERSION):
https://play.google.com/store/apps/details?id=com.ram.memory.booster.cpu.saver
The truth is that this application achieving control the use of RAM on my device, but I had to buy the full version, you can use the mode solves this problem, in short, once you buy the application must be enabled mode more stability and activate (Required root to use this application, it is a bit obvious that the application is called root Booster).
AutoKiller:
Before knowing Root Booster using this application but really saw that I closed many processes necessary but the truth if I won a big improvement in the management of RAM, the truth if you run install I recommend you select the Ultimate mode.
-Tweaks:
Truth does not recommend it Tweaks init.d but the truth if they help as much as elsewhere in scrolling speed or other you run.
L-Speed:
http://forum.xda-developers.com/android/software-hacking/tweak-l-speed-v1-0-02-02-2015-t3020138
This Tweak me if I worked well to improve the speed of scrolling and a little more open applications, RAM usage but saw no improvement truth in one or another section if that worked.
Now, this is the only tweak I can recommend for this device.
-Things not recommend:
Do not mix Tweaks:
Many would say that mixing Tweaks will gain greater speed, but not really. In some cases this may cause system instability, causing not work normally, can cause terrible lags or even a brick, do not think for mixing Tweaks will gain greater speed, if your system already works well with you Tweak to mix with more.
Do not mix apps:
I say almost the same as in the previous tip, if your device and works well with an application to modify that, the truth if mixed apps can cause applications to close or in some cases are playing something and that game middle parting closure.
Well, that's all I can tell you, as I said at the beginning of the post if you have any Tweak or application that worked them to control this might share? would help users much more control this big problem, I hope you enjoyed this post and wish them well controlling this great use of RAM in their devices,
Greetings.

1)The Huawei Kirin 970 chipset brings you a faster, stronger, and seamless smartphone experience. Its built-in NPU (neural-network processing unit) enables deep learning based on user behavior, ensuring your Honor View 10 truly understands you.
2)Because of AI technology, EMUI 8.0 understands how you use your Honor View 10 and allocates resources by anticipating your behavior. It’s always working in the background to make sure your Honor View 10 runs smoothly even after months of use.

That really didnt answer the question though. Just how will is anticipate what you are going to want to do? Does that mean the device will be monitoring everything you do to develop pattern recognition? How much of that info will have to be server side?
One example is it learns habits of apps you use in a sequence or different times. Say in the morning you get in your car, stream music with spotify, then use google maps for navigation, and so on. It will ensure those apps are easily accessible in memory and allocate more so they open faster and what not.
Since we are opening the APIs and the AI ecosystem, we are hoping developers will be able to take even more advantage of the NPU.

That is what I kind of figured as it would have to monitor what you do to learn. Looking forward to seeing how that plays out.
My laptop is dell inspiron core i5 5567, 8GB RAM and 1TB Hard disk.
Background:
If I'd enough money, I'd just go and buy a new laptop. But that's the problem, I don't have it. I've seen my friends doing very perfect for be it web development or app development in 128GB SSD and 512GB Hard disk(even now, few months ago, to be precise).
I'm planning to learn web development, make personal projects(I Don't need to host them to public professionally, heroku will do the job. And backups of codes can be stored in github once the project is completed) so that I can apply for jobs. The jobs that I'm applying are the same that university graduate in USA does. (Only difference is that they treat you like sit and pay sit )
I currently have a 1 TB hard drive. I still have 650-700 GB of space left on hard drive. Problem is that I've used it for more than 10000 hrs and the disk health isn't looking great either according to crystaldiskinfo and crystaldiskmark(Although crystaldiskinfo said "GOOD" health). (These problems are being faced since long time but I didn't code for more than 2-3 weeks so I didn't care that much at that time)I faced problems like even VS code used to hang, 100% disk usage would make me suffer(in a fresh installed OS, this'd happen even while not coding, it'll randomly happen like that. But not forever. If I restarted, then it'd be gone. But again after some time, it'd come. I'd tried everything given on the internet and forums about it and it wasn't fixed permanently->the only conclusion that I found is "Get a SSD".), Pycharm repeatedly kept crashing(no matter how many times I re-installed and re-setted up) and a general perception that I built was "Applications are getting optimized for speed of SSDs, and everyone must have a SSD for their C drive". I ignored it at first, because I felt like why should I get it? My laptop is dell inspiron core i5 5567. The SSD that I can put here will have speed of 62.5MB/sec. And even my current hard disk has similar speed.
I'm getting more speed in my 5yo hard disk than that'd come from my new SSD. LOL. (It's done on Ubuntu on small sample though). BTW which company's SSD is great? Is TOSHIBA's SSDs good? Do tell about that as well.

I can share the link to all the details of the problem I was having, and various other details which will only make this post unread-ably long if I post it here, if you allow me to share. It is in superuser website.
HENCE, I'm switching to hybrid storage with SSD and Hard disk.
Every penny counts to me and I don't want any underutilizations as well as risking not enough SSD space. (Storings data like music, images, videos isn't a problem in this case, because I've very less of them).
I can get a new laptop once I get a job with 1 year of salary.
Requirements:
Here's my software requirements. The storage are just my guesses, your insights would be valuable here.
1) Windows 10/11.
2) Microsoft Office Professional containing word,doc, ppt, excel.
3) Brave browser (Not considering downloads for browser. Downloads can go to hard disk)
4) Chrome browser
5) Firefox browser
6) images2pdf softwares
7) IDE(probably VScode or pycharm whatever supports web development and is easy to use for beginners)
8) Web development installations (for 1 stack like MERN, MEAN etc)
9) Viber/Telegram Downloads (Can be removed regularly on unwanted basis)
10) Save codes and notes on Joplin while learning. Notes will contain images+codes+text.
11) Note taking app on Joplin
Windows 11 would need 64GB, I don't think my laptop would support windows 11 so at max my windows 10 can go upto 64GB
MS-Office could take 4GB.
While most browsers take 100MB for installing but for storing cache, bookmarks etc I'm not sure how much would they be taking!
images2pdf type software would take 500MB. (I use online tools mostly but sometimes for special files and situations, I use this desktop application).
I'll need Joplin for note taking. It'd take 500MB+(size of Notes pdf). If I can install it in Hard disk, No issues at all. Can I? Is it possible? I'm going t use caddy and use both Hard disk and SSD at one laptop internally. I'll do the same for Viber and Telegram so that the downloads stay at Hard disk as they're not very important and in very less quantity as I don't have tons of people out there in Viber and Telegram.
I've Never done any web development so I'm not sure how much space learning any of those stack would take. Like space taken by django, a SQLserver etc. I'm not talking about exe file size but the size taken by them after installation.
My files storage requirements (of current,for storing datas like videos, audios, pictures,pdfs etc):
1) Important docs 34.7MB
2) Study materials that needs to be saved forever 41.5 GB ( I can instead just index the name of the book and download it later as they're all downloaded from online. More than 90% storage can be freed up from 41.5GB)
3) Very important courses downloads 103.16 GB.
4) Unimportant courses 206.1 GB (I downloaded them online, It's very less likely that I'm going to use them. They're not very important. But I could need them if a course is really good or if the topic is really tough and I need multiple insights)
So, I need around 110 GB of files and multimedia storage. I really don't want to waste SSD space by storing them so I'm instead planning to get 128GB pen drive for it. It's because I won't use this course heavily but they are useful. But I'm hearing things that pen drives are sit. Losing pendrives isn't the problem for me but it could instead be quality and durability. Original pen drives aren't generally sold here so loosing data could be a big risk with that.
For those unimportnat 2016.1 GB of course, I'd just keep them where they're currently at-1TB Hard disk.
HELP Question:
In my region, If 1 TB hard drive costs x, then 128GB pen drive costs 0.307x and 256GB SSD 0.538x and 512GB SSD costs 1.153x. I'm not mentioning budget because I'm not buying from amazon or any American/International sites.
Can you share your ideas about what should I do?
As I said above, this is My view:
1) Get 128GB pen drive to store 103.16GB of "Very Important Courses"
2) Buy 256GB SSD. 64GB for OS(Windows 10 as I don't think windows 11 will work in my laptop) and 192GB for files.
Is there better approach to this?
Remind me of things that I'm not noticing atm.
Extra:
While I've said this for web development, I really would love information about android/IOS app development setup required (storage only).
It usually depends on the work of full stack developer that how, much space he needs such as if you are working in gaming industry you needs more than 1TB because you have to run heavy game engines as well with coding so if you want to learn deeply about laptop for full stack developer, it will help you to understand your needs more deeply.
