The one that gets me is when you find a *server* running an OpenGL screen
saver like the pipes thing.  Every time a request comes in for the server,
the screen saver will have to be preempted, and the instant that the server
is done processing the request, the screen saver will be re-launched and
immediately fill up the cpu's cache memory with the screen saver code and
the OpenGL library, replacing the server code that is actually doing your
work.  The next time a request comes in, all of the server code will have
to get faulted back into cache again.

And people wonder why NT servers are slower than Novell, etc.

If your organization uses Windows based file servers, get up right now and
go look at their consoles.  If you find any animated screen saver running
on any of them, either disable it or change it to the simple "blank screen"
saver.  Instant cpu upgrade.
