(I've just seen Robs note, but I guess this still may be of interest. Sod
it, I've typed it so I'll send it :)

Hi all!

First message to this list, so please excuse me if this is a F-A-Q (though
I've checked the list archives and it's not apparent).

Speed on an idle Compaq 1600 2xPii 300Mhz w/512Mb RAM:
  Linux (2.2.5-15): Running the precompiled x86 MMX enabled code
= ~90k per second per CPU
  Winnt Server (v4 sp6): Running B.Gladmans MMX enhanced code
= ~74k per second per CPU
  Winnt Terminal Server (v4 sp5): Running B.Gladmans MMX enhanced code
= ~74k per second per CPU

(some other misc figures:
  Speed on a Dell 1300 2xPii 450Mhz w/512Mb RAM:
    Winnt Terminal Server (v4 sp5): Running B.Gladmans MMX enhanced code
= ~111k per second per CPU
  Speed on a Dell 1300 2xPii 500Mhz w/512Mb RAM:
    Winnt Terminal Server (v4 sp5): Running B.Gladmans MMX enhanced code
= ~123.5k per second per CPU)

I know that NT has an overhead - but goddamn! I wish that all my servers
were running Linux :( Any other comparison with OS/CPU combinations
available?

Any comments?
