  This may provide some interesting feedback to WGT.

  As I indicated earlier I have a dual cpu Xeon 5260 dual core;

  I was curious as to its floating point power.  Boy, was I astonished:

  This combo which I documented is capable of 44.6 Giga Flops per second.  My old motherboard could only muster 589 Mega Flops.  This board is a whopping 80 times faster.

  It might be wise to look at your code to determine where your bottlenecks are.  I still get inconsistencies from time to time. 

  I am sure my computer is optimized as best as it can be.

  How do I measure my flops?

  There is a piece of software you can try, its called sisSandra;  Filehippo has it.  Check the arithmatic cpu benchmark;

  Just in case someone wants to know what a flop is, here is an example;  Determining the natural logarithm.

  fldln2
   fld ab
   fyl2x
  

  Each instruction on the fpu is a flop;  FPU (floating point unit);  Flop {floating point operation}

  Thus there is 3 operations;
