CPW is not the same as CPU speed.
Actually, I think the correlation between CPW and CPU is very strong. A couple
years ago IBM began publishing two (2) metrics for evaluating system
performance. One was CPW. The other was CIW (an acronym for Compute Intensive
Workload). There was a very strong correlation between the two.
With regards to user based pricing, which seems like a good idea to me, how
does the OS define a user? Client Access connections are pretty strait
forward, and IBM has been monitoring Client Access Licenses for years. But
when a user is accessing the HTTP Server, how is that counted?

I am curious where are you getting the 8000+ CPW (commercial processing
workload) rating for a PC? CPW is not the same as CPU speed. I do know
my model 520 with 3,800 CPW rating running lots of concurrent services
and applications will outperform a quad-core PC server running just MS
SQL Server. We have an application that runs on a PC and makes
connections to both DB2 and MSSQL and reads data from both and the 520
responds quicker that the PC server.
