However much of a kludge HyperThreading is, and I don't doubt that it's a horrible kludge, performance on my 2.4 GHz P4 has improved dramatically since I enabled it. When I'm running two CPU-intensive programs at the same time--an extremely common situation--latency is much less of an issue. I'm really happy with the results, even if the design is awful. But when dual-core processors become affordable, I'd love to get one. -- Andrew McNabb http://www.mcnabbs.org/andrew/ PGP Fingerprint: 8A17 B57C 6879 1863 DE55 8012 AB4D 6098 8826 6868
