"The surprising part is that PostgreSQL 9.0.4 is more than 100 times
faster on this test than MySQL 5.1.49 with the InnoDB backend (186s
for MySQL, 48s for SQLite, and 12s for PostgreSQL). Postgre developers
seem to be doing something right."

If the speed is to be measured purely (and simply) on these numbers,
186/12 yields 15.5 (or maybe 16 if your round it up or 15 if you use
integer division). May be about 15~16 times faster would be more in
line with numbers provided.

Allan.

Congratulations, but those number are little bit unrealistic. 50 micro
seconds per query - maybe they use ODB caching?

I guess he did the math on MySQL, too. Could be worse; could have ran
into http://bugs.mysql.com/bug.php?id=33704 which, as you can see, is
totally not a bug.
