I really misread that. I thought you were complaining that your OpenBSD boxes didn't flush.
Maybe he meant that their performance was crap?
Note the icon - I know I started out to run BSD for my first server but somehow ended up with Debian, can't remember why. I've never actually run BSD but I do expect that it would be an experience that would have me (again) scratching my head and saying "why do people still run that MS shiteware?]
