It's now easy to use execution profiling to improve results. Without execution profiling, I get a speedup of between 5 and 6 percent. With execution profiling I'm getting over 10% speedup. I'm going to more tests, but so far I'm very happy with this. Andrew PS Thanks a lot to Vincent Diepeveen and Steffen Jakob for help with getting me to this point.
