Did you mean tickless system with "noticks"? I have this enabled ATM
deactivate that.
Even with that, there still are problems. With composite enabled, move
an mplayer window around and see how the video starts to skip big
amounts of frames at the moment you start moving and when you "drop" it
again. The compositor takes away CPU time and mplayer starves for a
short time. BFS solves this.
Also, have you considered that you got it all backwards? The kernel
configuration tells you that for lower latencies, you should use 1000Hz
and PREEMPT. It even says "Desktop" right there. Why should I take
your word over that of the kernel devs who actually wrote that code?
if that does not help:
And with extX I assume you meant the file systems? I'm aware that ext3 is
not very efficient with large files, but I can't/don't want to use ext4
yet because I need to access the partition from windows.
neither use ext3 nor ext4.
The I/O blockage has nothing to do with the CPU scheduler. Or at least
not much. The "GUI freezes during file copy" problem is another beast.
BFS doesn't solve that.
