Re: [ANNOUNCE] COMPCACHE on kernel-power
 

the best thing is to stick on the topic please
and freemangordon that's what i ment before
when reaching the internel swap N900 starts to lag till have to reboot

just an extra info
cgrouping in /dev gives a better performance than cgrouping in /sysparts

Re: [ANNOUNCE] COMPCACHE on kernel-power
 

I re-flashed my second N900 (rootfs & eMMC) and then installed just rootsh + Compcache kernel-power.
It seems to work fine. Some lagging when ramzswap is full, but still responding quite OK.

Other N900, (KP+CSSU+speedpatch, etc...) started to lag heavily after ramzswap was full and eventually needed a reboot (or battery removal). I tried with speedpatch installed / removed, results was the same. Something is confiliction with compcache.

I'll add CSSU and other stuff to clean N900 and check what will happen.

EDIT: Installation steps (cumulative)
1) CSSU installed -> OK, no changes
2) Swappolube installed and "proposed values" applied -> NOK (stop responding, battery removal needed)
3) Swappolube and just swappiness adjusted to 30 -> OK (better that proposed values, but lots of lagging when heavily loaded)
- Annoying lagginess starts somewhere when +50M flash swap is in use. Below that it is quite usable.
4) Speedpatch (speedpatch_0.4.deb) -> Best performance so far. Ramzswap full & +70M flash swap and device is very usable and lagging is very minimal ( I had to test this even agreed to keep it in separate topic)

EDIT_2:Copied same settings for the other N900.

EDIT_3:With the other N900 problems started again after some usage. Load averages are showing: ~10, ~8 and ~3, but there is no program using CPU more that 2% and CPU freq is at min (min = 500MHz, max=805MHz). This ghost loading is causing lack of responsiveness. Any ideas how to find out what is causing extremely high constant loading? Top and Conky are not giving any additional usable information.

...it is? Wasn't the kernel auto-scheduler patch first upstream included in kernel 2.6.3x?

@Gusse
you're using the suggested disksize?

Re: [ANNOUNCE] COMPCACHE on kernel-power
 

Yep. disksize_kb=131073

Re: [ANNOUNCE] COMPCACHE on kernel-power
 

Which is expected behaviour, once out of RAM (and notifications turned off, so memory consumption is suboptimal), we hit internal flash swap. The benefit is that we can run more applications before that hit. Lets see how it will behave once notifications are running

Re: [ANNOUNCE] COMPCACHE on kernel-power
 

So karam's patch adds upstream kernel patch to n900 kernel? Don't think so.

Again, stay on topic please. I don't want to further discuss speedpatch here, there is a dedicated thread for that. Thanks.

This gives me an epic boner.

Just sayin'

Re: [ANNOUNCE] COMPCACHE on kernel-power
 

Oh I swear to $DEITY that we should ban everyone that advocates this 200-line patch.
Nokia tries to do this and fails - see ohmd/syspart.
The downside to Nokia's approach is that it's too much on top of the kernel's SLUB. Nokia should've focused on making "nice" actually work. Most programs managed by syspart are small-memory-footprint programs that run in the background. Except for browserd and tracker (but that should be nice'd to 20)

Unfortunately, for some reason the device becomes unusable without syspart/ohmd.

Re: [ANNOUNCE] COMPCACHE on kernel-power
 

OH gosh Hurrian I swear to GOD that my device is usable
and pleeeeease stay on topic

i don't think that is necessary -_-
