performance issues with pre-release mainline version #43

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?

I just compiled the mainline version and I'm noticing that performance is
slower with this version than 0.6.   

Is this something known?  One thing I did is that I ported the
swap_free_notify code from 0.6 into the mainline version and it seems to be
working ok, but I'm wondering if that could be the cause of my performance
issues.

What version of the product are you using? On what operating system?

mainline compcache on kernel 2.6.29 on android OS

Please provide any additional information below.

mainline version is basically compcache-0.6 without swap notify support.

swap notify support includes:
 - changes in swap code to _throw_ notifications.
 - changes in ramzswap driver to _catch_ these notifications.

Are you sure you ported both these parts to mainline version?

Anyway, sometime in next few weeks I will sync up compcache code with mainline 
and
also add notify support (http://patchwork.kernel.org/patch/49054/)

Hi Nintin,

I have both sides ported.  Anyways, I removed some widgets and disabled the 
compcache
stats tracking and that seemed to have improved my phone's performance.

The swap notify stuff has been rewritten (currently in -mm tree) which should 
solve
any performance issues.
