Fixing lag in rezound running Infection 2.9.1
I thought that maybe others would benefit from my hours trying to find the reasons for my Rezound lagging. I am sure that many here know much more than I.
So this group of issues each helped improve my speed to now it feels like a fresh install again. I am running stock flyhalf kernel
1) Use LagFix to fstrim my partitions. I do a great deal with news apps and added/removing apps. Things got so slow in general especially when updates occurred in Play store. New installs now work great. Trimming made a big difference. Not all kernels support this. Be careful to have a backup before trimming--some have had bad results 1-2% of the time. 4.3 supposedly has trim built in. http://forum.xda-developers.com/show....php?t=2104326
2) Delete and clear accounts settings, contacts/calendar storage and cache. It seems that because I restored from nandroid or for some reason after being on the rom for a long time. Things got slow and some of my contacts would not sync. Also it seems that Exchange services even though not showing much usage in betterbatterystats was slowing down my Rezound. I think a sync was not occurring. So I did everything in this thread and again a big difference occurred and the entire device was more responsive. I cannot emphasize what a difference this made. The device would seem to lock up sometimes and then unfreeze. After this step, thinks were so much more fluid.
3) Apex 2.0.6 was having awful redraws lately. Seems it is this software release. So switched over to Nova for at least awhile. Now things are snappy again. I see that Apex 2.0.10 is out now so perhaps that fixed it.
I am using the original flyhalf kernel in 2.9.1 and have my clock at 96/1512.
A person may consider using Rom Toolbox or another tool like V6 Supercharger to modify OOM settings to a more aggressive stance as well. I tried this but then reverted back after 1-3.
Also it seems that some in the past have reduced redraws by using these settings in build.prop. I did not try this method either but was about to....
I hope this helps get rid of pesky lag for some. 1,2,and 3 each really helped my situation.
