Question CPU usage 100% when downloading

[vultusprime]

I have noticed that when downloading a large file or files, from the internet at high speed my CPU usage goes up to 100%.
I could be using emule, utorrent or just downloading files from steam or GOG, the result is the same. The application gets a very high usage and then other application bring the usage up to 100. Only when it has finished downloading, or I stop it, does it all come down to a normal level.
It's the downloading at high speed which causes this problem. Everything else works just fine.

I'm at a loss on what to do.

It may be worthwhile to update your network drivers if you haven't done so in a while as a starting point. For whatever reason network drivers tend to be flaky sometimes.

well, I could try, but I'd like to point out that this is a relatively new pc. Bought in May 2021.

You'd be surprised how outdated the drivers can be sometimes in a "new" PC.

My network drivers were up to date. What other options do I have now?

I have found the cause of the problem.
SOLVED!
