[FreeNX-kNX] Extremely poor performance with Youtube/flash

[Mario Becroft]

Update:

I got some oprofile output while displaying a youtube video and on my
particular system, it looks like all the time is spent in libfb.so in
fbCompositeSrc_8888x8888mmx

Running flashplayer locally, it also hammers the X server, but not
nearly as much. The frame rate looks at least 4x higher, yet the CPU
usage of the X server is lower. The only difference is that it spends
all the time in fbCompositeSrc_8888RevNPx8888mmx. Presumably this has to
do with a slightly different pixel format.
