Which field are you talking about Saul?

1. Use no more than: 99 % of processor time (at top of the Device Profile)

or

2. On multiprocessors, use: 99 % of processors (in the advanced options section)

For option 2, on a 2 duo 99% is rounded down to 50%, effectively permitting only 1 core. On a Quad that's rounded down to 75%, 3 cores of 4.

For 1, the 99% of CPU Time is next to useless. The client will run 99 seconds and pause 1 second.

The 60% is for temperature control i.e. the client runs 3 seconds and pauses 2 second for cool down. You're much better off if you have temperature concerns to use TThrottle, specially written for BOINC. Set a target temp and the client will be controlled dynamically.

The option 1 of course to use 99% of all available processors and believe me is far from next to useless; I have a P4 HT ( not even a true dual-core), 2GB DDR-400 this being half the power an average new PC has today, is a configuration that has proved to be very effective in my system, and no, the projects tend to drop from 100% (per-"core") in less than 99 seconds, I have observe it in the Task Manager Process Tab, and this is why it works so well, at least for me, I don't see why wouldn't it on more powerful systems.

I can do EVERYTHING, even load several web pages with Flash content and my PC won't lag, not one bit, I write out of experience.

Imagine how much Teraflops the WCG would get by doing this small change? and Laptops would never be compromised, everyone happy :)

So, is the new profile will be considered for addition?

Saul,

You can 'inofficially' and 'unsupported' create as many device profiles as you like. Find posts by e.g. Moonian on this topic. Whilst it works for you of which I'm pleased, it is not probable it works for someone else. At least, you've not convinced me at all that 99% of CPU time, not 99% of Processor cores/threads has a wide application. Post us the message start up log so we can see the processor threads actually used by your P4 HT.

60% of processor time in the default profile was btw chosen as same default used for the old UD agent, to include the safeguard of the device's temperature, regardless of how well dusted the cooling elements are maintained, wherever a volunteer is on the planet. The erring on the safe side so that no one can claim grid crunching broke someone's computer.

PS, my laptop duo shows 63% efficiency with throttle control.

Saul, as said glad it works for you. As for "attitude" and "you may have tried yourselves instead", I'll let that slide. I've asked for your start-up message log. Please add to that a screenshot of the Task Manager, Performance window that charts the CPU time for several minutes of BOINC running, during use of computer and during idle. That will show all interested the impact.
