Using "ondemand" rather than "performance" can do quite a bit for your interactive performance as well. With "ondemand" your CPU runs at half speed until you've stressed it for a bit. So if say, switching to another desktop takes 0.1 cpu seconds, but the threshold is that the CPU must spend 0.5 seconds working before it kicks into full performance then all those UI actions might only execute at half speed.
So personally, I have my desktop CPU (i7) running at performance setting. That was clearly noticeable for me for short bursts of activity. It's possible you could settle on doing that for just some of the cores (I don't know if that makes sense, since they're in a single package).
- Evbn 14y agoIt is extremely unlikely that interactive performance has any human-detectable relation to CPU switching from 1.5Ghz to 3ghz or whatever. The I/O and Ram paging situation far dominates.
- Strshps1MoreTim 14y agoThe problem is switching not occurring, or occurring too late - with the OS shuffling a single threaded app around I/O units it looks like the CPU usage is say 20% so no need to move to higher clock.
- darkstalker 14y agoIn my case the interactive performance when using "ondemand" is highly noticeable when gaming or while using some apps like Firefox. It seems to be a known problem [1] with GPU intensive tasks. [1] http://jasondclinton.livejournal.com/72910.html http://jasondclinton.livejournal.com/72910.html
