Thanks to all the people who posted info about how to compile with 8.1. Couldn't have done it without you!! Harold Naparst ID: 128887 ·

On one the newer version worked better and on the other the older one was a little faster. I posted the results in this thread. YAOSCW-N-r8.1 was done with ICC 9.0 YAOSCW-N-r7 was done with 8.1 I think. NOTICE: Correct benchmark test for optimized clients ID: 129091 ·

Not worth upgrading, wouldn't you agree? I really couldn't say. The variation in time may have been caused by something other than just the version of compiler. ID: 129629 ·
