Hi,

I recently upgraded my hardware. At the same time the OS was upgraded
from SuSE 10.0 to 10.2. Although the new hardware is about 3 times faster
than the old, performance of CVS in general and cvs rtag in particular
is much worse.

The total CVS database contains about 4,300 ,v-files taking 183 MB.
running cvs rtag requires almost 4 minutes (using pserver protocol to
the localhost). I didn't do any timings before the upgrade, but I'm
pretty sure it was *much* faster.

The CVS server is running at 1-2% CPU, mostly in status 'D' (blocked on
disk I/O), so the disks are the most likely culprit. Mount options are
here:

/dev/sda4 /home reiserfs acl,user_xattr 1 2

The drive is a SATA drive. The old drive was IDE using ext3. I don't
remember the details of the mount options and the hardware is gone. I
don't experience poor disk I/O under normal usage; just CVS appears to
be suffering.

As there are not many changes to CVS itself, I hardly expect that to be
the issue.

Old system was 32-bit, this one 64-bits. Both old and new are dual-CPU
machines. Old system had 2GB memory, new 4GB.

Any clues?
