Instead of the rather dodgy "Timing[10000!]" benchmark for performance, the following seems a better way of measuring the elapsed time taken to do a calculation (as Timing[] supposedly measures CPU time): In[1]:= start=AbsoluteTime[]; Print[Short[10000!]]; AbsoluteTime[]-start For the Windows 387 Version 2.2 running on a Compaq Despro 433i PC, I get the result Out[1]= 137 And on the DEC Alpha OSF/1 Version 2.2 version, running on a DEC 3000 Model 400, I get Out[1]= 13.59984 The "Short[10000!]" means that the timing isn't affected by the time taken to print 36000 digits to your VDU. What results to Mathgroupers get with this on their machines?
