Thanks for that bit. Is there a way that busybox' swapon would include swap priorities in a future update? That way we could omit the swapoff/swapon workaround.
EDIT: There's the mount package, supportingly with priority support for swap.
EDIT2: Said mount package has unmet python dependencies on my device. Bummer.

pls tell me that why compcache is better than swap memory as in compressing process cpu requires some time and doesn't that make phone operation slow...?

i didn't have any better performance with compcache
but reboots many reboots
@knobby
@seker_94
don't give sh|t about COMPCACHE
if you want extra performance just use speedpatch
but reboots many reboots

bumping -_-
i have a single question
Does COMPCACHE effect our n900 or it doesn't?

Compcache is kernel development, so it is not a trivial thing, and there are still issues to be resolved in the N900. Until they are, the real gain can't be assessed.

Please don't pollute this thread with senseless chatter. That script you refer to isn't a patch and doesn't affect performance in any way.

Anyway, I think it is worth trying compcache, and if we don't try, we'll never know. From the ramzswap stats in my N810, after hte initial phase, most swap usage is reading and not writing, so it is possible that we can get significant gains in the N900 too.

i am using a disksize of 65536
and have my swap of about 750mb on my micro sd card,
both with the same swap priority.
for me anything above 64mb causes the massive lag experienced by a few people.
thanks freemangordon for all youve done so far.
