First off, does anyone know of a way to get the maximum memory used of a
process? I'd like to add that to these results.
Fixed my suite of performance tests and reran them. Added a couple more
performance tests. These tests are ra_local vs local cvs dir. The
results are the averages over 3 runs. The perf test code is available at:
http://fishbowl.digitalbytes.net:81/svn/scripts/reposbench.py
Tests run on:
Dual 1.0GHZ P3, 1GB RAM
ext3 fs on ide hard drive ~36 MB/s max (hdparm -t)
Redhat 8.0
subversion-2002111212-0 daily redhat RPM (3758)
nullimport = import of empty directory
new = import
checkout = checkout
* These are all run on a wc with no changes vs the repository
localstatus = cvs -qn up vs svn st (CVS doesn't really have a
localstatus AFAIK)
serverstatus = cvs -qn up vs svn st -u
emptyupdate = update

As you can see, CVS is still faster by a large margin.
