The following is a selection of RC5 core/processor speeds on the 
various machines at my disposal. Unless otherwise specified, the 
core used is the one that was automatically selected.

The Clocks/key column is the number of processor cycles required 
to process one key. The keys/s/MHz column is the crunch rate per Mhz.
