[Mono-dev] GUID generation

I need to generate a large number of GUIDs. I tried with my laptop and a
.net console application and it can generate about 1million GUIDs in about
Then I tried the same with mono and it needed 3.4 seconds.
My surprise was trying on our Server (Intel(R) Xeon(TM) CPU 3.00GHz) where I
got the following results:
8 seconds to generate a million of GUIDs.
Surprinsingly my old Sun Blade 1000 took almost the same time (Solaris 10
SPARC): 9 seconds.
I guess there is a reason why .NET implements faster GUID generation but, is
there any other globally unique number generator for Mono/Linux which I can
use? Also, any idea why the Xeon (which is much, much faster than both the
laptop and the Solaris box) is so slooow generating GUIDs?
