PFC,
Thanks for doing those graphs. They've been used by Simon &Heikki, and
now me, to show our main issue with PostgreSQL performance: consistency.
That is, our median response time beats MySQL and even Oracle, but our
bottom 10% does not, and is in fact intolerably bad.
If you want us to credit you by your real name, let us know what it is.
Thanks!
