Re: Massive interactivity improvement under high I/O load!

You'll only notice a difference under intense I/O. Try writing a 2gb file to your SD card with the standard configuration... it'll tend to lock the device up. Then try it with these settings.

Re: Massive interactivity improvement under high I/O load!

I just put my settings near the end of /etc/event.d/rcS-late.

I'll be releasing a debian package soon as well.

Re: [Announce] EBD - Enhanced Backlight Daemon

I'm not 100% sure, but try disabling "power save mode" under Settings->Display, and see if that helps.



Can you paste the result of the dpkg -i line?

Re: [Announce] EBD - Enhanced Backlight Daemon

I think I can make that work. It was my original intention but turned out to be tricky because a lot of processes adjust the brightness level on various events.

At worst, I'll implement an applet...

Re: Proper vsync and reduction of tearing

Heh... I just noticed that. Looks like the SGX driver is closed source. How annoying.

At the moment, yes. :) I literally threw this script together in an hour just to get some feedback on the algorithm.

Re: I/O nr_requests

Careful; the larger the I/O request queue, the more likely it is you'll lose data on power loss or if your phone crashes.
