New The more you can do, the more they ask you to do
The big toys that slugbug and Scott play with have a reason for existing. People buy them, take them to their limits, and wish that they had more.

As for multi-threading being slow, talk to the good folks at Sun about that. Just because Linux 2.0-2.4 sucked at multi-threading, and just because NT has its problems, doesn't mean that multi-threading can't work well. You just have to do it well. (Linux 2.6 also should do it well. Along with scalability improvements, Sun is going to find itself outperformed farther up the scale...)

Cheers,
Ben

New Absolutely.
We're constantly maxing out that big machine. Incidentally, we don't exactly play with it... that's the production database machine. ;-)

With respect to multi-threading, again absolutely. The threading in Linux is currently atrocious. The scheduling is bad (although there are patches) and the signal handling is completely broken.

Tests I've done had Linux threading slower than Win2K by 20%, albeit without patching.
