| Hi Martin,
| Anyway, to summarize my findings on cvs2svn.py performance:
| 1. Use tmpfs for a working directory to avoid disk IO.
| 2. Use a LD_PRELOAD-ed library to get rid of useless sleeps in the

| 3. Increase the db cache size to avoid shuffling blocks in and out of

| 4. It may be worth changing the pass 2 algorithm to increase

Wow! I knew I was not alone :-)
Thanks, I will try that out... on another machine... I have only 256M on my workstation, running X
and Mozilla... I have a 1G machine lying around somewhere... :-)

I'll repost with my progress.
