Premium version is now ON SALE! -50% off of the price! Enjoy!
Some Android users suffer from poor performance after some days/weeks of heavy usage. This is due to a well-known TRIM bug affecting these devices (there are reports that some Galaxy Nexus devices also have affected memory chips). Users with -discard mount option are NOT affected!
The source of the problem is that internal storage is not properly TRIMmed when needed. You can find lots of information on XDA - http://xdaforums.com/showthread.php?t=1971852 and http://xdaforums.com/showthread.php?t=1929021 for example. It is also well-known fact that running fstrim Linux tool from time to time fixes the issue until internal memory runs out of free blocks. Other solutions like mounting with -discard or disabling fsync may be slow or dangerous.
LagFix is a user-friendly implementation of fstrim utility. It allows you to select which partitions to trim (you should leave defaults unless you know what you are doing) and run the process easily.
Please note that fstrim output depends on kernel and device. It works fine unless you see errors. You might see big amounts of bytes, zero amount or repeating amount. All are fine! Read fstrim manual to understand why all these outputs are valid.
It is also advised to reboot your device after the TRIM process so that kernel could reinitialize block data.
There are two versions of LagFix:
Warning! Premium version comes from different publisher! This is because Google does not allow to publish paid apps from my country. Send your rage to Google Both versions are legit, don't worry.

P.S. If your ROM mounts /data with -discard then this app is NOT needed!
P.P.S. Free version is now attached for those, who do not have market for some reasons.
