I was just looking at the CPU efficiency score for my summer cruncher (Reprisal), and I was wondering how it's calculated. I know that it has to do with how much of your processor time goes toward BOINC. For instance, if you run a ton of other programs, it will be relatively low.

I have three questions about it, though.

1. Is it a "recent average", like RAC, or is it a snapshot your efficiency as it was when the last benchmark was taken? I would like to squeeze all I can get out of the computer, so the former would be more helpful in giving me a useful figure to see what my changes do...

2. Does this take into account times when the computer is running with BOINC turned off? For example, if I temporarily turn BOINC off to run something like a backup script, would that lower my efficiency?

3. Does it take into account time spent doing tasks that are considered "overhead", like downloading WUs, running benchmarks, displaying graphics, and task-management? I know that these operations only take a minimal amount of resources, but I'm picky...

I'm trying to figure out how best to optimize a computer for models/hour, and the "CPU Efficiency" stat sounds like a very useful tool for this.

Thanks in advance!

Thanks, that answered my questions. I searched the forums, but I didn't think to look there. It's bookmarked, now. :-)
