I have had a chance before to compare single-threaded processes on
hyper-threaded xeon cpu's versus pentium III xeons. In all cases the PIII
performed better.

The same is not at all true for multithreaded applications. So I am not
really
surprised with your finding.

Try it with MT disabled. And you are probably only using one of the cpu's.
