desktop. Keep in mind the theory behind HT. In a very simplified nut shell
you take one CPU and make it two logical CPUs.(more or less) So it will not
make a 3Ghz CPU any faster then a 3Ghz CPU. Where you do see a difference is
everything seems to respond just a little quicker due to there are twice as
many logical CPUs to service CPU requests. This can be seen when windows
starts up the lag between seeing your desktop icons and windows being
useable is much shorter with HT.
I had a problem with some apps crashing (Norton anti-SPAM) with HT on. To be
fair to NAS it would crash weekly anyway, with HT on it would crash daily.
Donna, are you replacing a desktop or a server? If you are replacing a
desktop I would not go with a dual CPU. Unless you have some mad money just
sitting around. Your desk top apps are more then likely not written to take
advantage of dual CPUs.

Thanks Jim,
I am now considering dual processors - just not sure and want to get
as much feedback as possible before diving into putting the new system
together. I am hoping to order parts Thursday and build this weekend.
If anyone has ANY comments on their system and what kind of
performance you get please feel free to post - or email me off list.
Thanks again,
Donna

I like it - it definitely improves performance response time when using
multiple applications. But really only for those applications tuned to
multi-processor performance to begin with.
CF won't benefit nearly as much as it will from dual CPUs (a dual PIII 1000
would I think give a single P4 3Gh HT at least a run for it's money if not
beat it outright under load - and probably costs about the same), but it
will definitely benefit. My workstation is a P4 3.06 GHz with HT enabled
and my development server is a Dual PIII 1000 (running at 1100).
This doesn't really have anything to do with memory however - just
performance. HT won't do anything to help a memory hog - only more memory
will do that. If it's a choice for CF always go with with more memory
rather than a faster processor (in general).

Okay - I fried my motherboard last weekend and have decided to build a
new system instead of replacing the old one. I've been running a
950MHz with 1 Gig of RAM for a WHILE now, and I am READY for some
speed now.
I had in mind to build a P4 3.0GHz and have been looking at the
HyperThreading technology. Heard it's great for memory hawgs like CFMX
and the like.
Anyone else using Intel HT technology? Any comments/suggestions
welcome.________________________________
