Wow! Amazing performance! I've just followed your steps to put ED on a dedicated ext4 partition as explained here and I can really feel a very good improvement while interacting with heavy software like Libre Office, Iceweasel and Inkscape. The UI, specifically, is way more responsive now.

But the loading times that I'm getting are nowhere near what you got (33-36 seconds to perform a cold load on LibreOffice Writer with 2GB of swap on SD restarted a few seconds before doing the test). I'm using Kernel-Power, BatteryPatch (max 805Mhz, left keyboard slide open and LCD turned on) and SpeedPatch. Surprisingly (at least for me) enabling Swappolube with proposed settings increased the loading time of the same test to 52-57 seconds!

I believe that CSSU-thumb should make a good difference due to lower memory usage by Fremantle apps, but I'm asking myselft if such huge difference couldn't be also because I'm using armel repositories while you may have tested with armhf ones? Or maybe some LibreOffice-specific configuration file that I missed?

n900_, which one of the Estel's image did you use in this test? I'm currently using the ED image debian-m5-sulu.img.ext2 (dist-upgraded to wheezy) on separated ext4 partition on eMMC.

I'm very excited to achieve similiar performance results as you demonstrated in the two videos by following your steps.
