Indeed, mysql 5.0 has poor scaling compared to postgresql (this affects
reads but severely affects writes). However when I tested the latest
beta of 5.1 about 6 months ago I found it had about 50% lower
performance than 5.0 in a read-only configuration. Maybe they had left
some debugging enabled or have since fixed it.
One thing that mysql can suffer from is the lack of row level locking
for MYISAM tables, I found that to be a write performance killer with
multiple concurrent accesses.
INNODB is supposedly better.
This was innodb, afaicr.
