F7 installer running very, very slowly [resolved]

I thought it worth posting the solution to this problem for anyone else 
with a Dell Poweredge 2300 server.

There is a bios setting for CPU speed.  The options on the server I am 
working on are: 450MHz and "Compatible".

I had switched the original 450 MHz CPU for a pair of 550MHz CPUs.  To 
get the server to recognize them I had to set the CPU speed setting in 
the bios to "compatible".

For whatever reason, that seems to mean run extraordinarily slow. 
Switching to a 450 and using a pair of 450 CPUs solved the problem. 
Machine is running very nicely.  Currently working through the F7 install.
