Using Linux saves the CPU!

Well, actually, Windows 98SE will execute HLT if you have ACPI enabled when you install it. Just look in your Device Manager and look for ACPI. For my P3, this cools just as well as any CPU Cooler software.

But Win98 obviously does execute some tasks when it loads, and even once you get to your desktop it still usually launches a few new tasks. Obviously it was running some kind of tasks, at least it was running Powerleap.

I'm just wondering, not trying to prove/disprove anything here.

If you keep that kind of experimenting up you'l recive a letter from the "Deep fried Cpu's Club" any time soon!!

well .. i think that Linux too (and any other OS for that matters) will execute some tasks when loading and after.

Well, I don't think Powerleap CPU Panel would use 100 % of the CPU power, it would be pretty useless if it did! I think the CPU load is no more than about 30 % after the startup. (Of course at the startup it is 100 %).

I made another test yesterday, with Win98 and Win2000. Apparently Win2000 sends HLT to the CPU, because Powerleap CPU Panel didn't want to do it, neither did Rain. Win2000 didn't crash the same way as Win98, it just rebooted the computer suddenly without complains. But still it crashed. Why on earth doesn't Linux do it?

I do believe I alread have said that NT4 and Win2k send HLT instructions to the CPU.

Of course Linux executes some tasks at startup. All I'm wondering about is how Linux handles the CPU scheduling, etc. If, perhaps, it doesn't dedicate all the CPU to some tasks even though they could use it all, whereas Win98 would maybe give it 100%.

I wouldn't think that would be a great way to write a kernel, I'm just wondering.

Your CPU usage is hardly EVER at 100%. Except for gaming, and compression. Even during startup, your CPU is probably spending more time waiting for I/O than it is processing.

Wombat, you forgot SETI crunching, and Genome@Home
