This is absolutely fascinating to me. I mean, over a year ago I saw the following post:

No, its less accurate this way, due to the fact that the clock cycles that the otehr programs use are not tested for stability by P95/orthos. I can get orthos to run longer by having my music playing and browsing OCN, as opposed to running only orthos.
When I read this, I decided to test this out to see if it was true for me too, and I found that it was absolutely true.
So, ever since then I have been running stress tests with everything disabled that would steal CPU cycles while I'm away from the computer. Some of those things include Windows Update, the screen saver, Anti-Virus, etc. And today with Windows 7, this now includes the Desktop Slide Show and the Gadgets. I also use the Classic theme as well. In fact, I made a specific theme that I named "Stress Testing".
I can't include the Power Options in the theme's profile, so I also have a habit now of making sure that no Power Options are set to automatically do things while I'm away, such as turning off the monitor or something.
So in other words, I am guessing that I probably wouldn't have to do all of this if I just set Prime95's Priority to 10. But if I did that without putting my computer in a stress testing mode (as I guess I call it), then I wonder what would happen when I stop the test after letting it run for 12 hours. I mean, perhaps everything that would
have automatically run will suddenly run the instant I stop the test.
I don't know, really. But after giving it some thought here, I think I'll stick with the way I'm doing it now because all I have to do is this:
- Close the clock Gadget (it's the only Gadget I use)
- Right-click a neutral space on the Desktop
- Press 'R' for "Personalize" (or just click it, of course)
- Select my "Stress Testing" theme (where I have just a solid color for a Wallpaper, the Classic theme, and no screensaver)
- Change the Power Options so that my monitor never turns off (it's the only real power option I'm using)
- Disable Windows Update
I mean, it sounds like if there's nothing happening that can steal CPU cycles, then there's probably no need to use a higher priority. Plus, the Test menu in Prime95 appears instantly with a Priority of 1 as opposed to waiting like 5 seconds or something with a Priority of 10.
Yeah, I know: big deal. hehe I mean, I know I could still use a Priority of 10 on top of preparing my system for stress testing, but when Prime95 is the only thing using my CPU, I get the feeling that it wouldn't make a difference.
Hmm... so I guess I just need to stop being lazy and do my own testing to figure this out. Edited by TwoCables - 6/18/10 at 1:39am
