Greetings all,
I performed some timing tests for 2.5.44 mm3 and ac2, using
tar zxf of the 2.5.44 tarball and rm -rf of the resulting tree as the load.
I performed each of these 4 times. There was some variation between runs,
but not as much as between kernel versions. This data comes from the
first of the 4 runs in each case.
The hardware was a single PIII, kernels were UP, PREEMPT.
All partitions are on the same disk, a ST340016A ATA.
For mm3, SHAREPTE was not enabled.
This is not intended as a comparison between filesystems, since each
is on a different part of the disk. But the reputation for reiserfs
to be able to delete files quickly seems deserved. The side-by-side numbers
are intended to show the amount of regression for each fs.
Yes, I know it would be nice to compare plain 2.5.44 too, but there is
only so much time in the day.
