[Asterisk-Users] P4 processor with Hyperthreading and Asterisk

[mattf]

Hello,

I read an interesting article on 2cpu.com that talks about the performance
differences between a P4 processor with Hyperthreading(HT) enabled and
disabled.
http://www.2cpu.com/articles/ht_explored/index.html

The bottom line of the article is that processor intensive applications
greatly benefit from HT being enabled, but memory intensive applications can
actually see a slight decrease in performance if HT is enabled. I have tried
Asterisk on the same machine with both HT on and off and haven't noticed
much difference in overall performance. 

Is Asterisk's high memory usage canceling out most of the performance gained
by using HT? 

And the best question is should I spend my money on a dual Athlon machine
instead of a P4C with HT?

Thanks,

MATT---
