thanks for the quick answer
i have bitcoin running, gomez peer and BOINC.
there is definitely a major slow down.
if i have bitcoin running, and click on gomez icon, it takes a good 30+seconds to open. should be instantaneous!!
I also run Bitcoin, Gomez Peer and BONIC ( World Community Grid ) on 2 of my older XP machines. However, they are duel core, So I set Bitcoin to use just 1 Core and BONIC to use 50% resources. I rarely hit 100% CPU usage for both cores, even with additional application usage.
You should try to find a good balance between CPU usage, productivity, charity and economics.
