[ slow deleting of 25GB, horrible latency ] Hmmm, I'd be curious to see how 2.4.9-ac16 (or 2.4.10) performs there. The reiserfs delete code should be scheduling enough due to transaction stop/starts that interactive performance isn't that bad. You should be able to repeat your results by doing the same tests on sparse files: dd if=/dev/zero of=foo bs=1M count=1 seek=250000 -chris
