Almost the same but the one i meant is setting screensaver to 'blank' instead of 'none'. justs give you the blank black screen.
thought you may prefer this as it clears the screen like boinc is suppose to when set to instead of leaving the boinc graph or the desktop on all the time.

al long as everything is sorted it doesn't realy matter.

Ah, yes. I see the difference now. Makes good sense. Thanks again.

Well, it's not all that surprising... most everyday tasks on the computer hardly use much of the CPU. Playing MP3 files on my system doesn't even register a percent of CPU usage (Winamp shows 0 CPU usage currently). The soundcard is doing all the work in this case. Most other things only cause momentary spikes in CPU usage. That's why if it wasn't for something like BOINC running, the System Idle Process is going over 95% most of the time.

I completely acknowledge that. I know a lot of the things i was doing wouldn't have made any difference, but there were things that a was doing at times that should have. like i said i did some (about 45 min) photo editing in photoshop because my sis wonted some diffrent effects on her wedding pics. I'm no expert but i know that some of the processes i used are memory and CPU hungry, specialy on large files.
Most of all for me was, i use dual monitor and watch music vids more than the mp3's (i use visualisation with those too) and i know video files can take a steady 15-30%+ depending on the quality.

I wasn't expectin much but i still think it should have added at least 30-60min considering some of those apps. i might try waiting again and set up a simple (but long and hungry) 3D render. that realy would make it interesting.

The CPU Time of a WU is not the elapsed system time. It is the time the boinc application gets to execute on the CPU and is independent of CPU load.

That is correct. I was going on the assumption that he was talking about the amount of real time/system time that had passed to complete the work, but it might have been an incorrect one. But, yes, if it takes an average of 5 hours to complete a WU and some process of higher priority steals the CPU for 30 minutes during the middle of processing a WU, it will take the system 5 hours and 30 minutes of real time to finish the WU. But, the CPU will still have only spent the same average of 5 hours actually working on the WU.

Agreed.

My 5 Linux systems just crunch away at optimal speeds - all day, every day.
