I was wondering what cases it would be advantageous to not have hyperthreading. For example, at work I use a P4 2.26 GHz w/o hyperthreading and at home I use a P4 3.4 GHz w/ hyperthreading. My work computer runs my simulations quite fast, with CPU usage going to 100%. I run the same simulations on my home computer and it actually seems slower, and the CPU usage stays right around 65%. I noticed the same thing on my other Celeron D processor as well. Is this a CPU issue or a software issue?
