Hmmm: 

        --hyperthreading doesn't work very well with linux, unless the
kernel and apps are specifically written for it
        --even if the kernel and apps are multi-threaded, hyperthreading
only adds 12-15% performance
        --the two 1GHZ processors are probably PIIIs and the 2GHZ cpu is
probably a PIV, a 1GHZ PIII than a 2GHZ PIV; 2 1GHZ PIIIs are much faster
than a single 2GHZ PIV
        --if the 2GHZ cpu is a Xeon it is a bit better....
        --the 2GHZ system may have faster ram, dual-channel ram, 64bit
buses, etc.

I would personally go with the dual PIII 1GHZ system.  PIIIs were much
better cpus for the most part.

2, 1GHz Processors (P3)= 1.6GHz (you loose approx 20% by going multiple
processor)

1, 2GHz Processor (P4) = This is a P4 which means it should have
hyper-threading. 

If you go dual, you can process 2 simultaneous threads at a total of 1.6GHz.
If you go single 2GHz, you still get 2 simultaneous threads, but at 2GHz.

I'm building an IDS network, I'll end up with about 6 snort sensors feeding
back to a snort server.

The snort server will be running:

Linux
mysql
apache
snort
barnyard
acid/base
open aanval

There are 2 servers available and I've been given my choice.  Basically, the
servers are the same with regard to memory and hard drives.  The difference
is that one is a dual processor system with 2 x 1 GHz processors and the
other is a single processor system with a 2 GHz processor.

I'm kind of leaning towards the dual processor system, but I wanted to see
if anyone had any suggestions before I made up my mind.
