I'm tired of teenage 1337 skill0rz PHP hackers who go "whoaah, 0ms!"
after running "select count(*) from forum_posts" in a single thread (the
developer himself testing his app), and then claim "MySQL rocks! I
tested the postgres 7.1 that came with <insert linux distro of choice
here>, but it was twice as slow!!!! Postgres sucks!"

Ask them what they know about concurrency: transaction isolation level,
MVCC vs. locking, and how they do when they test OLTP performance in
highly concurrent scenarios, and I'm sure you'll get a "huh?" as an
answer.

Kids...
