Crunching WU's for Seti@Home

[MrSanderzX]

Curious, I have been reading that RAM past 64 MB makes little to know difference for crunching WU's for S@H. Is the speed of your WU's completion dependent on your processor? I am very curious to the dependencies to speed up the crunching of WU's for S@H. Thank you for any light shed on the subject.

SETI@Home is mostly affected by 5 factors that I can think of:

1. CPU speed
2. frount side bus bandwidth
3. memory type
4. memory latency
5. L2 cache size (up to 1MB)

For PCs that are just sitting there running SETI and not doing anything else, 64MB is fine, however, if you are running other apps, 64MB is probably not enough. And that will be true whether or not you are running SETI.

We have lappies at work WIn2Kpro, that had 128M RAM. Several people love to multitask and see how many windows of different apps they can have running at the same time, then complain because the PC seems to be slow. Bumped em up to 256M RAM, sped things up, because of less HD swapping. They are still complaining about things though, mainly because they are looking for a way to get rid of their Dell PIII750mhz laptop and get an IBM 1Ghz laptop. :Q

Just as an example, switching from 256k on chip L2 cache, to 1 meg on chip L2 cut almost 40% off the processing time!
