Yep, and those Suns are running NetBSD iirc. As somebody else has
mentioned, this has a lot to do with the maturity of the operating systems
at the time these services were implemented and the experience/tastes of
the systems administrators involved. It has nothing to do with _current_
performance benchmarks whatsoever.
Many of the less-clued *BSD advocates use examples like this of major
services running on their particular flavour to "prove" that it is "quite
obvious" their flavour is superior. But the real issue is that these
services are running fine, the admin know how all the components of the
systems are working together, and according to the problem-solving
flowchart the next steps are "don't fuck with it" -> "no problems".
Hotmail/Microsoft had to learn this the hard way.
I have no doubt whatsoever that a current Linux system run by competent
administrators put to the same task will tear strips off NetBSD. But
there's simply too much cost involved for Hotmail to switch. They've
been there, done that, and got fried like a chicken.
