Some info to share: db_STRESS Benchmark results

Folks,

just wanted to share some benchmark results from one long performance
study comparing MySQL, PostgreSQL and Oracle transactions throughput
and engine scalability on T2000 and V890 (under Solaris). Oracle
results are removed (of course :), but other are quite interesting...
Findings are presented as it, following step by step learning and
tuning curve :)

So well, you may find:
 -  http://dimitrik.free.fr/db_STRESS.html  - Benchmark kit description
 -  http://dimitrik.free.fr/db_STRESS_BMK_Part1.html  -- first main part
 -  http://dimitrik.free.fr/db_STRESS_BMK_Part2_ZFS.html  -- second
part including ZFS specific tuning

Tests were executed in Mar/Apr.2007 with latest v8.2.3 on that time.
Due limited spare time I was able to publish results only now...
Any comments are welcome! :)

Best regards!
