Actually, a 2.4 could have HT. "Intel extends Hyper-Threading Technology? to a variety of desktop PCs, with the new IntelŪ PentiumŪ 4 processor, featuring an advanced 800 MHz system bus and speeds ranging from 2.40C to 3.20 GHz. Hyper-Threading Technology from Intel enables the processor to execute two threads (parts of a software program) in parallel - so your software can run more efficiently and you can multitask more effectively." ----- Original Message ----- From: "Brooks Davis" <brooks@one-eyed-alien.net> To: "Jens Rehsack" <rehsack@liwing.de> Cc: "Andrey Chernov" <ache@nagual.pp.ru>; <freebsd-current@freebsd.org>; "Lukas Ertl" <l.ertl@univie.ac.at> Sent: Wednesday, July 09, 2003 10:07 AM Subject: Re: HTT on single CPU?
