[SOLVED]Very high system load on an RPI4 - Ubuntu 20.04.1

Using a Raspberry Pi 4GB, when trying to download anything - my CPU usage is always at 100%.
I've tried turning off crc check, as well as others in the performance tweaking section and nothing helps.

I'm not using an SDCARD, I'm booted from an SSD with USB3 to SATA.
Have enough memory and swap:
total used free shared buff/cache available
Mem: 3.7Gi 497Mi 1.4Gi 129Mi 1.8Gi 3.0Gi
Swap: 1.0Gi
I'm out of ideas. anyone?

PS: I'm using the latest stable 21 from your site - have also tried docker and it's the same!

PSS: the high system load can go into it's 20.00's. right now with Firefox open, I'm at 0.70. this changes when running nzbget and goes into the 20.00's.....

HELP!

Downloading from Usenet requires computational work. High CPU usage is normal when the download speed is high.
What's your download speed?

It's happening again!
Ubuntu 21.04, was using the stable release but trying the testing release atm to see if that fixed it!
I have a 350mbps line.
It wasn't going over ~5 load now it's 10+........

Just a note for others!
Make *sure* you're *NOT* using a lot of connections. I have several servers setup and using 5 connections each and not going past a load of 3/4~ now.

Thanks!!
