Memsscore http://mems-score.org/ benchmarks the (today mainly inertial) sensor subsystem of smartphones without expensive test equipment (right now just a printer is needed). But be warned, you need some time to understand and execute the benchmarks. Furthermore it interacts with hardware components (camera and sensors) which always has the risk that on some phones you will see issues.
We would love to get feedback from you on
- Does the app run properly on your device?
- Have you been able to perform the benchmarks? Is there something which would have made it easier for you to understand how to perform the tests?
- Any ideas for additional benchmarks are welcome. The requirements are reasonable reproducability and only minimal equipment must be required to perform the test.
Also the benchmark becomes more useful if we get benchmark score from many devices.
Many thanks

Hey
I installed JFMStudios GPS Performance on my S710 but unfortunately it didn't run on it Said the .exe file couldn't be found or not all modules are available or something like that. Installation went smoothly and I checked the folder there PPCGPS.exe on Program Files/GPS Performance. Still no run.
Could it be because it's made for WM2003...? I have tried googling the web for similar apps but no luck.
Is there other such programs available and if someone has succesfully used JFMStudios' app on Vox please tell me how you did it.
Short description what JFMStudios GPS Performace does:
GPS Performance is a must have application for people with performance cars interested in performance statistics. Using a regular GPS receiver and sophisticated alorythms, GPS Performance is able to accurately measure 1/4 mile dashes and 0..60 timings.

Not compatible
HTC Vox is not listed as a compatible device. Nor is any other smartphone as far as I can see, so your answer would be no, no chance of getting it to work.
Damn
I take it that there are no similar apps from other developers either?
Until you posted I had not even heard of this particular application. I have to wonder in any case how accurate such measures could be given the inherent lack of precision in the GPS positioning: small variations in the position data across such short timings would have a huge impact on the reported speed and acceleration data. In normal driving conditions i.e. standard navigation programs, any errors in speed are averaged out but for such an application it strikes me that you would not get much time for that. Still, it is an interesting idea.
Good luck in your search!
I have now researched the various 'ROMs' (actually firmware), and have narrowed the field to four. I'd like input on these. Priorities are (in order):
1. Complete Stability. I've run TomTom on WM5 for 6 years, and outside of TomTom it's a real mess. WM is so buggy I can't use it confidently for anything other than nav.
2. Good Battery. I have a friend who just got an Evo, and he says battery lasts only ~3 hours. I'm sure that's because of the large display, but also I read that several ROMs and apps really sacrifice battery on the N1. One screen I want to have dedicated to some sort of CPU/Mem/Storage monitor, so I can easily check it.
3. Lots Of Cool Features. It seems that video at 720p might be problematic as I gather it's really 3Mp upsampled, and/or it disables the still camera/flash somehow? Kernel optimizations are nice, although "deodexing" is not defined -anywhere-. I'm unlikely to stray beyond the UI built into the ROM, as it could introduce instabilities.
a. CM6 - The Big Kahouna. This ROM will likely be supported for a long time and is likely to integrate the newest kool features over time.
b. MoDaCo - Its thing seems to be stability, although a feature-by-feature comparison with CM6 leaves me confused, much less comparative usability is impossible to determine. Kitchen allows preclusion of G**gle apps.
c. LeoFroYo - The guy seems to know what he's doing, so under consideration. Comes with G**gle apps tho.
d. Kang-o-rama - an innovator whose improvements have been co-opted by others.
e. RoDrIgUeZsTyLe - I like it, but it is clearly very ill given the thread comments. Rejected.
Really? Nobody knows anything about this?
it depends on which phone u have bro, u didnt even specify that
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...?
Again since Sensation XE doesn't have people promoting seeder too much, I brought it here for those who are not familiar with this.
Please don't post negative things here. I only understand theory of this mod that's all. And I held no credit to any of the content.
Requirements:
1. S-Off
2. Custom recovery
3. Rooted
4. Init.d Support for flashable version
CREDITS FIRST:
lambgx02 (for the original seeder and APK format) http://forum.xda-developers.com/showthread.php?t=1987032
ryuinferno (for flashable version) http://forum.xda-developers.com/showpost.php?p=36479461&postcount=1924
FAQ:
What is seeder?
Its a mod that increases resource in your device so it wont suffer any starvation(lag).
Above is the easiest way to explain it.
What is the difference between APK and Flashable version?
APK version provides more options to tune method it provides resource and the frequency of it.
Flashable version will be automated in your device as long as your device have init.d support.
How can you prove it significantly improves performance?
Well I can't really tell, Dev's in sensation department is extremely good all ROM's are well tweaked. Its good enough without it, but IMHO it will be better with it.
To .zip version user only
Once you flashed it. Go to terminal emulator. Enter
su
seeder
A menu will show up. It will indicate if seeder is working in your device or not.
Thank the developers of this awesome invention, then Thank me if you think its good for me to bring it here.
Cheers!
TIP: Try on those high load games, the loading speed improvements are the best ways I can see after using this.
good
downloaded the app using the QR code and never installed. wheb you select it tin the task bar it doesnt go into the instalation menu. however when i went to the downloads in my phone it opened the installer. it tried too install but took a very long time. but in the end worked thansk made a slight difference to the lag on my phone. :good:

Although this improves performance slightly, the only thing it really does is run your CPU at a higher frequency. This'll cost precious battery life.

Can't say you're wrong at the battery life part. But IMHO, it doesn't actually touches the frequency part. Frequency is something that runs instructions, but this thing provides additional resource aka fuel for your device. It don't make your engine combust quicker, it will only make your engine combust cleaner, and more fuel that's all.

I'm just going to leave this quote from a CM maintainer here:
“IMNSHO the recent entropy pool fad is bull***. The only users of /dev/random are libcrypto (used for cryptographic operations like SSL connections, ssh key generation, and so on), wpa_supplicant/hostapd (to generate WEP/WPA keys while in AP mode), and the libraries that generate random partition IDs when you do an ext2/3/4 format. None of those 3 users are in the path of app execution, so feeding random from urandom does nothing except make random… well… less random.
The only conceivable reason some devices may feel faster is because by constantly polling the PRNG, it keeps the device’s I/O in constant use (which in turn, depending on device, will make the CPU stick to higher clock frequencies to keep up and/or ramp up the IO scheduler).”

Don't get me wrong, if it seems to help for you, that's great. But I'm not going to use it.

I promoted this because it seemed great on my previous device. But in sensation the effect is much lesser than anticipated. Works in my friend's S2 though. Maybe its for low end devices only tsk tsk tsk.
But still, no harm experimenting on everything.

Seeder was designed for older versions of android. It is stated in the thread that it is solved in newer versions of android.
nstall both apk but antutu doesn't see the 3d bench and always ask to download it, therefore there is no test button, but only down load but that brings you to the market with missing antutu
Why try to run ATuTu 3D Bench?
The issue with it is that it doesn’t actually judge a device based on its overall performance and experience, it just runs theoretical tests on individual components of the SoCs or some other individual part of the whole device. OK, these are not always wrong, they do suggest the capabilities of a CPU or GPU up to a certain extent but are wrong interpretations for the combined system’s performance and experience, IMO.
still you have't been useffull after all these sspeech
