Has anyone tried to run two CLI's at the same time in a single P4

that has a Hyperthreaded CPU?  Do the two argue over resources?
It works fine, yes they do argue and that means that each workunit
takes a bit longer but since you are doing 2 at a time it more than
makes up for it.
Use something like SetiDriver to do it, it is easier.

In general, how much slower is WU results than when just one is run?
My son has HT and he slowed about 25% from the single unit speed.
He went from 2 hours for one unit at a time to 2 1/2 hours per unit
while doing 2 at a time.

I've got a P4 3 ghz, 1 gb ram running only seti at the moment & it's best 
time is just ove 3 hours. What do you use to get 2 1/2 hours? 

FIRST you need to get rid of he screen saver version and switch to the
CLI(Command Line Interface) version. Get SetiDriver while you are at
it. It runs the CLI seemlessly and provides the capability of a local
unit cache too.
Then you need to get rid of ANY screen saver, they just take
processing time to run away from Seti. Think power button on the
monitor!!
