Here is brain drain...

I have dual PPro200 running linux, inside that I have VMWare NT4 server.  
(Why? because I can!)

Now... the Linux OS is running 2 threads of DNET one per processor, the 
VMWare NT4 Server is running 1 thread.  So in all I have three threads 
running.  Using personal proxy Analyzer - I show the two "machines" Linux 
and VMWare NT4  - 526204 (10.51%) and 520455 (10.36%) Key rate (overall 
% of my network rate).

I would expect that with this setup it would run slower than Linux with only 
two threads... Overhead for VMWare and NT... but in reality it comes out 
about 2% greater. 

I would love to know why... but I don't want it fixed, I like the little extra.
