This looks good, but does performance suffer on the N810?

I've just tried it, and it really seems to work. I can run more applications at the same time with less slowdown or freezes.
We now have N900-like multitasking
I've got just one problem: the "ramzswap" swap has lower priority than default maemo swap, so it's not used. I've got to manually swapoff/swapon the maemo swap to lower it's priority.
Also the last sentence in the GUI help is really confusing: there is no button on the left and i'm not sure i understand what's its talking about.

, its for the Fremantle version which will support the backing swap usage. I know about the lower priority on the swap, there really is no fix to it, since swapon on Diablo doesn't have the priority switch.

Cool, good to know, I'll put the priority in the Fremantle version.

This sounds great. Is there a chance that it can be used on the 770 too? This would give the old device a new life.

Looking at revision: http://code.google.com/p/compcache/s...57d374b2e8503#
It says 2.6.12, so if 770 has a kernel newer or equal to it, then maybe it is usable. I know that the UI and initscripts _should_ work on it
Calling the community to compile and test this, since I don't have a 770. I can of course modify this software if needed (or anyone else).
EDIT: the original thread that I helped Nitin Gupta to test his fix: http://compcache.googlecode.com/issu..._test1.tar.gz], so that was the first version to work on my N810, please try to compile this if possible.
EDIT 2: oops wrong file

I'm proud to present you the second version of Ramzez, the controller for a kernel module called compcache (ramzswap now). This release features a GUI to control the amount of memory to use with ramzswap and automatically loading the modules on boot.
For the current release go to:
http://garage.maemo.org/projects/ramzez/
If you ever modify the amount of memory needed, just restart the device so that the modules pick up the new size.
I am planning to do the next release on Fremantle too so that we'll get this feature to N900 as well.
If you would like more information on compcache please visit: http://code.google.com/p/compcache/
