I have an older phone (HTC Desire Z / Vision) which is still usable, but it has been extremely slow lately. When I say slow, I mean that applications take 10-30 seconds to open and I often get "application is not responding, force close / wait" windows pop up. I thought it was slow CPU speed, but after running top I find that the problem is spending too much time in IOWAIT status. CPU is overclocked to 1.5 GHz, I am running Cyanogen 7 (newer won't run on this hardware). I ran some benchmarks and got these numbers for disk access speed:
Internal storage write: 3.18 Mbytes/sec
Internal storage read: 15.5 Mbytes/sec
External storage write: 2.69 Mbytes/sec
External storage read: 16.7 Mbytes/sec
Is this especially slow? Is it causing the problem? If not, then what else could be causing the problem, and how could I fix it?

Probably might need to just do a factory reset to get rid of all the clutter on the device. Also it maybe because the phone is running out of available ram. Also since you're running a custom rom and most likely a custom kernel try this http://forum.xda-developers.com/showthread.php?t=2416441 and yes it is meant for pretty much every phone.

The phone isn't running out of available RAM, Android's memory management does a good job of keeping RAM clear for use by programs. At any rate, a reboot clears all RAM but doesn't fix the slowness issue. It's that the CPU is spending far too much time in IOWAIT state, which means waiting for disk access.

In my opinion Android does a pretty horrible job at memory management. Also I said factory reset and not a reboot. Factory reset usually fixes 90% of the problems that may occur in android.

Amazing! I don't know what that did, but my phone now loads Google Maps in less than 5 seconds! It used to be 30 at least and always get the Wait/Force Close window! Good job, Bangladesh!

Thank You For Your Appreciation.
:good:
Well, it appears I spoke too soon. Seeder helped my phone run well for about two hours. After that, it went right back to being slow again. Very disappointing, I thought I had this solved.
What else can I do? Other than a hard reset, which frankly I doubt will fix this problem.
If I did a hard reset, would it fix the lag problem? What are my other options?
Greetings,
I'm currently running Cromi and have become interested in Rom2SD
From what I understand I need a sandisk ultra (30mbs) card which is a minisd
Then I install a version of Cromi with Rom2sd and install another version,
I read that it makes the tablet snappier/faster,
What I don't understand is why
Is this linked to the tablets 1gb memory?
Would using a 16gb memory card allow me to use 2-4gb of memory and increase response/peppyness
It lags frequently making it undesirable for use
You can look at it this way:
Imagine you have a computer or tablet with two hard drives (or SD cards) installed. One is cheap slow memory resulting in slow read/write speed, the other one allows much faster read/write speeds.
Which one would be better suited to run your system?
With rom2sd you basically install a better and faster SD card to your tablet (in form of a microSD). You install the rom and all your apps to the faster card resulting in better performance. Your old (internal) card is still accessible as storage but has (almost) no role in the actual running of the system.
Does this make sense?
BTW, if you are running CROMi-X on internal and your tablet is sluggish you should investigate why. That's not normal and whenever a user reports lag on CROMi-X it always turned out to be: one dirty flash too many, outdated bootloader, user installed apps - or something similar.
Personally I get better Quadrant scores with rom2sd, but in my day-to-day operation I don't really notice a difference between the two. At least as long as I keep fsync off on internal

Indeed I'm still on 5.2.3 odex from Dec 16 and running internal with fsync off and I don't get any lags at all. In fact I would say that the tab is running extremely smoothly
Hmm Dirty FLash??
I reset after reboot would that help?
Is it advisable to reformat SDCARD as well?
How can I check bootloader version or update?
I thought Cromi-X came with bootloader or I might have missed a step,
Is it recommended to update bootloader -> Clean INstall Cromi-x?
If so how should I go about, currently on Cromi-X newest Release, used twrp to install last week
Appreciate the input and help, tired of my girl who uses a IPAD 3 talking smack
I have opposite experience to those mentioned here.
Yes, CROMI-X runs very very smoothly right after install.
But after a month or so, it is so unbearable i have this moments when i am just about to throw it out of the window (3rd floor) and save me some stress using it forever. It annoys me so much i want to scream sometimes.
I don't know what it is that it slows it down so much, but from 700€ tablet i never expected this in first place.
Example:
opening chrome - sometimes fast, sometimes slow
immediately trying to stop loading of the opened page as i don't want to wait for it - but before it registers my touch sometimes takes 30s or a minute
pressing address box for manual input - another minute or more
waiting for keyboard to actually show - another minute
typing an address - another minute
By this time i am already annoyed and just press power button - more luck next time.
And this goes on and on and on.
It is weird as sometimes it really is fast, but than, most of the time is just waiting and waiting and *****ing.
If someone can tell me what apps could be slowing it down, i would appreciate it.
Bad karma tablet all the way.
Hardware: Verizon HTC One M8, Gunmetal Gray, with a Sandisk Ultra 64GB microSDHC card (Class 10)
Modifications: Rooted, S-OFFed, TWRP 2.7.0.2 and ViperOne(M8) installed @ version 1.3.1, Firmware, Radios and hboot updated from Santod's uploads. Installed Viper4Android FX v2.3.3.0, using "High" quality driver. I've modified the EQ curve a bit, but made no other changes to effects. It's only enabled for headphones.
Problem: Occasional glitches when listening to MP3s via Google Music (and only experienced when using headphones so far). I'm not playing from the cloud; the MP3s are stored on the microSDHC card. Seems to occur every 20 minutes or so, within the first 10-30 seconds of the start of an MP3. It's not at the same point each time, and I can't repeat it on demand or I would assume it's a bad copy of the file. The glitch is a very brief but very noticeable gap/hesitation in the file that's playing, like it's rebuffering or something. It only lasts a tenth of a second or so, but that's plenty long enough to be noticed.
I'm tending to think it's a problem with Viper4Android; next step is to uninstall it and see if things improve. Not sure what I'm going to do for EQ without it, though.
If anyone has thoughts to share, they'll be appreciated.
I've been experiencing the same thing. I've tried several different audio players but there's little difference; there are skips in tracks played off external storage. I'm on stock rom, with faux kernel. I experienced this with a completely stock device. My gut feeling is that the issue lies in the sd card, I have been trying different i/o schedulers and read ahead cache values. Some combinations have helped slightly but not enough to eradicate the issue, it could even just be coincidental.
I'm going to go ahead and say it has nothing to do with the rom, and it shouldn't be a cpu issue like I've seen on other devices since the glitch occurs regardless if the phone is awake or not.
Same here, playing off the sd card it will skip

Wow, so I'm not alone. I'm surprised I didn't find more hits on this issue when I searched; perhaps my google-fu is weak.
I couldn't imagine it being hardware related; this thing is orders of magnitude more powerful than any of my old MP3 players. I guess I'll live on the bleeding edge with ROMs and new kernels to see if it clears up. Thanks for your feedback!
Happens on my stock rooted/s-off using Poweramp
I'm pretty sure it has to do with the CPU being used too much. I was messing around with different clock speeds and trying to see how low I could take it and still be usable, and the lower I got, the more and more glitches came up.
Also, it is not just for mp3's. I get the glitches on spotify too, so I'm assuming it has to do with the overall audio output process, not just the reading of music files.

I'm inclined to say it is not a cpu issue, as I haven't encountered any problems using music stored on the internal memory.
I've been giving this issue some thought, and did a little research (probably not enough to talk authoritatively, though ). I've come up with the following observations:
This issue appears to have surfaced with Kit Kat.
Wiith Kit Kat, Google made some significant changes to the handling of external/removable SD-cards; no more direct write access to them from applications.
A lot of media player applications were "broken" by KitKat and needed to be redesigned to support the new restrictions.
The standard protocol for moving files to the removable SD-card is now MTP.
Which raises the following questions, at least for me:
Does this mean that MTP is the protocol for accessing MP3/media files from player apps, and therefore there's now an arbitrator/server in between the filesystem and media players?
Now that direct write access to SD-cards has been restored via an edit to /system/etc/permissions/platform.xml, is there a chance that an older MP3 player may have better luck playing MP3 files, given that it would probably use direct filesystem access vs. going through MTP (if in fact MTP is used for "new" applications)?
So it's not just me? It doesn't happen as often for me after the ota

You're doing god's work, man. It would certainly make sense if mtp was the reason behind all of this, as mtp is generally broken and incapable of parallel tasks. Perhaps, then, there is some kind of operation that the OS is performing at fairly regular intervals that disrupt what should otherwise be a simple read. Media scanning? Entropy generation? I'm not really sure, but clearly there is something silly going on in the I/O. Maybe a programmer like @SSukk could shed light on this
I think part of the problem is the amount of storage on the larger cards, and/or the fact that they're just not fast enough . My 64g card is a ultra and has problems. I bought one of the faster extreme pros and have never had any problems even when fully loaded. It's only 16g though. When the larger cards get faster speeds well see this disappear entirely.

A microSDHC card doesn't have to be very fast to keep up with the demands of playing MP3s. MP3 players were using much slower flash memory 10+ years ago without glitches or skipping.

I think you're onto something. I'd love to get some input from someone who understands the nuts and bolts of media playback in Android.
I have Google Music playing from the cloud on occasion, but most of my playlists are cached to SD. I don't use anything to modify output other than leaving BoomSound on, and I've not run into this glitch with headphones or Bluetooth,
Bump!! Wanna see more answers to this question! Haven't put MP3s on my phone yet but already installed a 64 GB card for the intentions on doing so!
Had mine in airplane mode for a while this morning as I was traveling to NYC. If anything, the glitches seemed to occur more often. I don't think they were predictable enough to say with authority that airplane mode was related, though.
Just curious, how are everyone's cards formatted? My 64gb is fat32, apparently. I suspect this to be a problem, even though it wasn't on other devices. However, I'd like to see if we all have that in common before I reformat and have transfer 60 gigs of music back over...

I didn't format mine after installing it, and I'll bet it came formatted as ExFat. I'll see if I can find a way to verify and report back.

I used this to figure out how I was formatted: https://play.google.com/store/apps/details?id=com.sylkat.AParted
Mine's definitely ExFAT.
On a related note . . .
I was sitting in the Stage Door Diner at 33rd and 8th Ave this evening (no, that doesn't really have anything to do with this issue, but it injects a little bit of local color into the story . . . I live in Maine, but I love NYC ), browsing XDA on my M8 while stuffing my face. For no apparent reason that I could see, a toast popped up with "Preparing SD Card." Now, I wasn't doing anything specific that would be accessing the SD card; as I said, I was just doing a bit of web browsing. But I thought that toast normally displayed only when the phone was booted and/or plugged into a computer via USB (and nowadays, with MTP being the default transfer mechanism to the SD card, it normally isn't seen then). But it looks like some process was doing something that caused the SD card to be "prepared," whatever that means, and since my music is on it, I'm suspecting it might have an effect on playback if it occurs when listening to MP3s.
Has anyone else noticed this symptom during normal usage?
Hi guys, I have a situation with my moto g, I have the 8gb version since one week, I've installed a 128gb sdcard on the phone formated as internal storage... During a few days I've no problem with performance at all.... Then yesterday I decided to encrypt my phone and today I loaded 60gb an data, music, photos and videos.
Since then my phone is struggling from time to time to do simple tasks like opening an app or dragging the status bar down... Is nothing like that happens always or with the same apps.... Is random, sometimes I just wanna to unlock the phone and it takes like minutes for the keyboard to come up.
Anyone with an idea of what this might be? Was it the encryption? Should I give the phone time to index all the data?
I know it's not a problem from the SD card, because it's the fastest sandisk that I could get.
Since you asked in the form of a question, I will give you the best answer I can based on your specific questions...
This is probably a multitude of issues... first, setting up your SD card as internal storage will typically show down performance, although sometimes not noticably. Second, you encrypted internal storage (your SD card) this slows down your system as well. Third, you loaded 60GB of data, music, photos, and videos, which will take a VERY long time to index and put into the Storage and Media databases, and there databases also reside on the internal storage, which access to has been slowed down significantly due to being on an SD card and encrypted. These 3 things combined will likely give extremely poor performance, for a time at least.
My first question would be how long has it been since you loaded that 60GB of data? On an idle device it would take several hours (maybe days) to index it all and update the databases...
Thanks, I might have precipitated myself in thinking that something was wrong, yet today the phone locked it self a few times, one time the process system stopped responding... I will wait until tomorrow if the problem persists I will try deleting the biggest folder ( music 40gb) and if I see some improvement I will add the music in steps.
I'm pretty sure it was the encryption. My phone, with a similar setup (1GB/8GB phone, 64GB SD as internal storage, reasonable amount of media) also showed a gigantic speed loss when I foolishly enabled encryption. I tried to work with it for some days until it became clear the situation wouldn't get any better. After a factory reset, formatting the SD again as internal and copying the media again, the phone feels even faster than it was out of the box.
I've also my phone encrypted for quite a few months now (did this already on lollipop), with actually no real complaints. However since a few days I've noticed huge performance hits as well. I'm also considering a factory reset...
Thanks for all inputs , I have restored the phone without encryption and everything runs smoothly again.
Hi, I've searched and seen many posts on slow sd's, and separately many posts on sd corrupting pics and vids, and I seem to be observing both.
The sd card is a 95mbps Samsung (uhs-1 class 10 u3) , phone is an lg g6. Phone is fine (non rooted), and all apps were working fine. Then when I started pointing apps to the SD, I noticed transfers were extremely slow (I'm only getting between 4-10mbps up and down), and in some cases things were breaking like vids, pics, and off Spotify not loading, line map downloads failing.
Ithink what is happening is the os or the SD formatting with a low buffer, is causing the low speeds, and then the apps can't handle the slowness somehow. Like if I take 10 photos quickly and video, the buffer to storage is so slow that it thinks they've failed or something.
Anyways, would appreciate any help because I feel like I've just wasted 40 dollars on an SD card.
On a side note looked wide and far to find out the G6 sd specs, to no avail other than a forum poster saying their device took the uhs-1 class 10 ok.
