I used Linus' "bigfile torture test" in the background:

while : ; do time sh -c "dd if=/dev/zero of=bigfile bs=8M count=256 ;
sync; rm bigfile"; done

and Theodore Tso's "fsync-tester" to benchmark interactivity.

Didn't save any results, wasn't expecting that this could be of any
further interest (but can run the tests one more time, if desired).

Thanks,
Heinz.
