Tim ran the WAC run. I have the actual log file from the run.

He used two machines on ICC. A single-cpu 600mhz workstation and a dual-cpu 600mhz workstation. I have output from _each_. The dual was only about 1.5 times faster as that version used the hash table lock (interlock exchange) that is terribly slow on alphas. We later cleaned that up with the current lockless hashing to get the performance back up to normal... > >>Correct, but you have to factor out the gcc vs MSVC advantage since both of the >>tests I quoted were with GCC... >> >>That changes things a bit.
