I think we all know that HT is one of the best things Intel has ever done as a company. All my servers use HT technology

Don't really want to turn this into a ht argument, but I'd like to see some supporting evidence of the various criticisms of ht we see so often. As an example...from here (has single threaded benchmarks with ht enabled) http://www.sharkyextreme.com/hardware/cpu/article.php/3261_1500631__1 Quote: >> We also wanted to examine if leaving HT enabled had any performance penalty with certain games or applications. This amounts to a concern that competition for CPU resources could actually lower the performance when compared to a standard 3.06 GHz Pentium 4<http://www.sharkyextreme.com/hardware/cpu/article.php/3261_1500631__7#>wit h HT disabled. We tested all of our benchmark applications in both modes, and while the majority of the performance increases were nominal, all of the benchmarks performed better with HT enabled. This is big news, as the design obviously allows full CPU partitioning, and gives users 3.06 GHz of power for a demanding games, dual-threading for supported application, yet still allows multi-threading and multi-tasking advantages in standard business use. >> On 10/6/05, Marcel <[EMAIL PROTECTED]> wrote: > > Hi, > > afaik you just need to put a "noht" to your kernel parameters to disable > hyperthreading.
