Load averages and multi-threading

milo64 · 2014-06-27 07:10:25

I've seen a website saying about load averages.
I have got a dual-core laptop here.
So, when the website says 2.0 means that the Dualcore CPU is exactly full of processes.

But I have multithreading enabled, so it pretends that there is 4 cores
So, is it dangerous if it gets to 2.0 or would it be considered dangerous if it gets to 4.0?

Sorry, the question may not make sense. I really need to go and learn my piano lesson now

Hi, simply said, if you have 2 cores with Hyper-threading (not multithreading) your computer would see 4 separate cores. If the loadavg shows 4.00 4.00 4.00,(always) it would probably be perfect, it's constantly working 100%, get the max out of it.
Of course, this is not ideal, you would like to have a machine not reaching this high averages.
You need to intrepid this numbers, the loadavg consists of 3 parts, the 1min, 5min and 15 min part, measured every 5 seconds. The first part mostly is the highest number, this is the 1 min.part. If the last part(15 min) is always the highest part reaching higher then 4.00 in your case, then it wouldn't be bad, but, I would say, time to look forward to new hardware for the job, although, it might still function fine, without lag F.I. Si, if your AVG sometimes spikes, no problem, if it does frequently, then it;s your choose, if the spikes go of the chart, time to buy new;)
BTW. It never gets dangerous, overloaded at the most.
