Yes, I know a few people that reports it works well for them. How ever for me
and some other do not. System is redhat 7.2, ASUS A7V MB, /dev/hda is on promise
controller. Following helps a lot:
while true; do sync; sleep 3; done
How did you modify the params of bdflush? I do not want to suspend i/o buffers
nor disk cache..
Another thing to notice, the X server has almost every time some pages swaped to
the swap space on /dev/hda. When bdflushd is flushing buffers X server stops as
has no access to the swap area during i/o lock.
