It is't. It is >certainly "around 2.8." It is closer to 3.1 as I have said... all persons who run tests at quads and just calculated the speedup from that, they always get other speedup results than you post here. Should they run it 5 times and pick for each position the most positive results out of it? I am simply not trusting you to proof any speedup number. Speedup numbers posted from you in articles assume a certain speedup and extend upon that. > > > > > >> >>-- >>GCP
