Seti Times

Can anyone tell me why it's taking my Athlon 800 over 15 hours to complete a Seti data unit when it only takes my old Celery 400 10 hours?
I decided to benchmark them by starting data units at the same time on both machines, I disabled power management and screensavers and left them to get on with it. How come the Celery finished 5 hours quicker?
I just can't work it out.

Are they using the same version of SETI? I heard that the newest versions seem a bit slower than the older ones...

Yup both were using V3.03
Wierd stuff huh

Does one have more ram then the other? Does one have more programs running in systray? For it to be accurate, make sure each comp has the same amount of RAM available with SETI not running, then run it and try which one goes faster.

SETI is almost as memory intensive as it is processor hungry. If you're running PC-100 memory or have less memory, that can lower output time. Also, SETI finishes quicker if you don't display it as a screensaver.

I'd say you probably just have too many apps running while SETI is running. I only run SETI by itself when i'm away so I get pretty good times. If you run SETI while you're also playing games or doing other intensive activities, then your times will always be pretty high.

Well both machines have identical 128mb sticks of PC-133 memory and I never run it as a screensaver. I thought it might have something to do with background apps so made a clean minimal install of WindozeME for each machine and installed only Seti on each. The celery 400 still came out 33% faster.
I'm gonna try it with Win98SE to see if that makes any difference.

Maybe Celerons have a purpose for that and Athlons have a purpose for other things http://www.opentechsupport.net/forums/wink.gif

Hmmm, I think this may explain some stuff:

Found this table at Nova's link in the OTS SETI thread in the Off Topic forum. This was just an average taken from Ars Technica's Team Lamb Chop SETI Benchmarking Page (http://www.teamlambchop.com/bench/index.htm).

Interesting numbers...
