My wifes new Gateway is the same! I do NOT like the Celeron chips!!
Over however long SetiQueue does its averaging my wifes 2.4ghz Celeron
is at 7 hours 28 minutes.
We have the same setup you do.
I even did some tweaking from this web page: 
http://www.distributedatmurc.co.uk/articles/setiguides/optimising.htm
and it did not help.
MY AMD 2800+ is pumping htem out is about 2 1/2 hours. It has a 512k
L2 cache! I WILL NOT do Intel right now!
Although my sons Dell laptop, 8500, has the Pentium M chip with
a 1 meg L2 cache and he can do 2 units in 2 1/2 hours.
He was doing 1 unit in 2 to 2 1/4 hours but now runs 2 units at the
same time, so he took about a 1/4 to 1/2 hour hit, but now does 2
units in 2 1/2 hours!

I just put together a system using the following:

PC CHIPS M22LR w/Celeron 2.4Ghz 128K
DDR PC2700 256MB

I expected to see the CLI knock out WU's in 2-3 hours, instead
I am getting ~8 hours. I have tried tweeking the memory settings
in the BIOS but nothing seeems to make a difference.

I also made sure that all the power/screen saver elements are
disabled. Any ideas?
