i agree but in this case, i think the 'problem' is not due to android OS itself (since my Galaxy Nexus yield no such problem) but more of a hardware 'defect'.....now i put quotes on the word defect because technically, the hardware in question, which is the flash storage in itself, is working and not really 'breaking down'. However granted that Asus uses cheaper flash memory with pretty bad IO speed, i think it's pretty much that there's not much we can do about it. I don't think RMA from google will help too. For now, all we can do is apply all these minor hacks and tweaks and hope that their component quality selection will be much better in future nexus devices.Turning off fsync which is done in Franco kernel or some other receipts for buttery smoothness is no real solution as it may cause data corruption. Device should be able to show acceptable IO performance without this tweak.

I have to admit, I loved my N7 since day 1 and would sing to its glory, but the lag is getting a little annoying. For example, this thing simply cannot download an app in the background and install it without hanging the whole system. I mean seriously, my G1 was able to do that and the Fascinate I have laying around the house that's what, 3-4 years old now...no problem. I can't sync email while browsing the web, etc. So even though I have no other issues at all, I might be calling Asus today. This is simply getting too bad and there is zero evidence that Asus or Google is addressing the issue.

So from what I can read here we're not yet clear on whats causing the slowdown/lag issue but with many thoughts linking this to free space?
My Nexus is:
- 16GB UK Version
- 1.8gb of free space (having deleted lots of stuff now now I've forced Google play/music to work in the UK)
- stock ROM
- not rooted
- has nothing odd loaded (twitter/facebook/onenote/a few other bits etc) and all from the official play.Google.com store except flash and BBC iPlayer (sourced from this forum)
Seems there may be other theories other than ram and io speed issues, but (and having called/mailed for support), both Google and Asus don't acknowledge these issues, yet the internet is rife with tails of woe like ours here!
So my question is - what are we able to do about it? Is here a way to en-mass register a complaint, surely there is a is patch that can fix this that Google can issue. I can't believe h/w is at fault here as the device isn't that unusual I.e same components in many other manufactured devices. Yet something is wrong, perhaps a petition, any takers?

So I don't know how many of you have seen this, but Google just asked if they can see some of these Nexus 7s that are lagging. Obviously neither universal, nor something they've figured out the cause of, yet. Mine isn't lagging since the factory reset I did, but those of you who are suffering might want to hit this thread and offer up your devices if you don't mind them having your data. Apparently they'll ship a replacement ahead of time so you don't need to be without your tablet.

It's a surprise Google didn't realize the lag in their internal test, unless Asus provided different hardware(like SSD) in different time...
#/system/bin/sh
#remount /data for faster i/o
mount -o remount,noauto_da_alloc /data /data
#disable fsync (controversial, I've been doing it for years with no real issues)
echo 0 > /sys/class/misc/fsynccontrol/fsync_enabled
#set zRAM size (change the 512 to 1024 for a full 1GB of swap, I use 512 because I'm on an 8gb and space is precious)
echo $((1024*1024*512)) > /sys/block/zram0/disksize
#use busybox to create and activate zram0, if busybox is not in /system/xbin, modify accordingly
/system/xbin/busybox mkswap /dev/block/zram0
/system/xbin/busybox swapon /dev/block/zram0
Looks good! How much free space on your device? And, could you please
mount | grep /data
We know that the discard option has been added, but has it been implemented?
Edit: About my sig. If my sig size overrides my helpfulness, BY ALL MEANS block me *rolls eyes until they come out of socket*
mmc: set emmc vcore voltage to 3.0V
per EE's request, set eMMC core voltage to 3.0V.
mmc: core: new discard feature support at Samsung eMMC v4.41+.
Support discard feature if MID field in the CID register is 0x15, EXT.CSD[192]

This patch is released from samsung.

k I don't mean to be a **** but, if you're filling up the complete 16 GB's and noticing a huge drop is performance why are you filling it up completely then? wasn't this a huge issue BEFORE the tablet was release? weren't people complaining "oohhh its not enough space for me to do what I want to do with it, i wish it came with an SD card". Google wants to promote CLOUD storage. If you don't want to store **** on the cloud and yet still loading the thing up with 100 movies and a million apps than that's your damn problem. This isn't supposed to be a high performance machine where it can store that much garbage and perform like a ferrari for you. remember, google wants to promote cloud storage.
