The machine has plenty of memory (128 MB).

Here is some more data.  I rebooted Friday a.m.  Since then:

CPU Uptime:             21:00 hours
RC5 CPU time:   18:30 hours

In other words, RC5 got 88% of the available CPU.  But the key rate is 
about 1/2 what it once was, before upgrading to Windows 2000.  I did 
upgrade to 2.8004 to 2.8007 at the same time, could this have something to 
do with it?  Running

         dnetc -bench rc5

says that Core #2 (RG Class 6) is the best at 1.8M keys/sec, and that is 
the core that was reported to have been auto-selected.
