I tried my Intel 3.0GHz processor on an Intel D865 board with hyperthreading enabled in BIOS for FC3 but unfortunately I failed to start the system until it disabled in BIOS back. So I forget about hyperthreading under Linux. But I heard that you can re-compile the kernel with this facility. Please ask this question from FC mailing list.

I need to replace a older HP DL360 server that runs squid for about 2500-3000 clients. This box will have raid1 for system and then 4 extra disks for cacheing (standalone, not raid). It also has 2 processors (3.4Ghz Xeon / Hyperthreading) and 4Gb of memory. I was wondering ...Should i have hyperthreading enabled or not? I've been reading along somewhere that some people say that hyperthreading does not work very good with squid ...any hints about this ;)? Kær kveðja / Best regards, Finnur Ö.
