CPU Time for Solve

I have obtained similar results. CPU Time for solving a 100*100 Random
coefficient linear system is:

19 seconds Mma 2.03 Mac IIci with Cash 
39 seconds Mma 2.1  Mac IIci with cash

By the way, the same test takes:

3.2 seconds Mma 2.0 on HP 9000/360
0.7 seconds Mma 2.0 on HP 9000/750 (PA Risc)

I don't understand why the Solve routine has slowed down in version 2.1????

Maybe WRI can comment! 

Conrad Wolfram will be visiting at the end of the week and this is one of
the questions at the top of the list!
