Subject: [gentoo-user] 100% CPU load is different to 100% CPU load?
Date: Tue, 9 Jun 2020 11:17:28 +0200	[thread overview]
Message-ID: <20200609091728.lgiekzccyqw4pgln@solfire> (raw)

Hi,

yesterday I md5summed my hole system with find.....|
xargs....md5sum....

With options I set xargs to use all 12 thread and use as much args per
call as possible in one line.

After a while I checked the CPU with glance and it shows, that all
12 cores/threads were "loaded" with 100% each constantly over a
period of about 1h. The CPU temperature rises to about 47°C.

The CPU does not contain a GPU. Graphics goes extra.

Today I created again a CPU load over a comparable duration with
a constant 100% CPU load on each core/thread.

Interesting it does not take more than 3 minutes to reach 65°C CPU
temperature.

Both temperatures reflect the die temperature.

What is the difference between 100% CPU load and 100% CPU load to
create such an difference in temperature?
How is X% load calculated?

Cheers!
Meino
