Kali Linux high cpu usage

Our associate is not being rude, Kali is designed for one job and one job only Pent-Testing, it is not designed for use as an everyday desktop, and doesn't guarantee to support any applications not available in the repository provides [see the full kali documentation]
Oh, sorry for saying that :sweat_smile: I didn't know it...
have you had this problem from day one or has it recently started,?
if recent, what did you install before it started playing up? [a new application,an update etc]
Did you install timeshift or similar,
well, I installed blueman and started using bluetooth... after that the problem started. Later, the problem became significantly reduced. and now, whenever the CPU gets too hot, or I use youtube or stream movies, the problem starts...

Aha - USB Pendrive - that’s almost certainly the cause of the slowdown.

The actual problem is that the USB bus can only handle a certain amount of simultaneous throughput.

If you’re running a LOT of intensive processes, especially if they’re performing a lot of disk read/write operations, then some processes will eventually have to wait for other processes to finish their read/write operations before they can access the disk.

So you’ll potentially see huge slowdowns when the system is really busy. Especially if you have any kind of persistent volume on your USB stick. (E.g. a data partition for saving documents, settings and data).

Eventually, it may seem like X is crashing. It’s not, it’s just that there are so many processes waiting to read/write to/from the USB stick and there are loads of processes stalled. Eventually it will just keep building up and will go slower and slower.

You will have seen a similar kind of effect if you’ve ever tried to copy multiple, simultaneous batches of files to a USB stick.
That's really the case of mine.
Are you using Kali for a security related course, or career? Or are you using it as your daily driver, for everyday use?!
Actually, my friend was using kali for security related course.. then when I asked him to install me a distro of Linux, he installed kali and that's what I kept on using...
If you want to run all of the things at once, then install it to an SSD or HDD, which can deal with more throughput!
ok, got it... Thanks a lot, sir!
 
I use youtube or stream movies, the problem starts...
This could be just the start of your problems,
As I said Kali is NOT designed for general use, it is what can be considered a minimal specialist distribution , made for one job and only that job pentesting, not as a daily desktop,,
It is not Kool ! it is a Tool.

If you want to learn Linux and use it as a daily desktop, forget Kali, and use a distribution compiled to do the job, there are hundreds to choose from but if you stick to one of the Debian/Ubuntu family you will find it easier to adapt to as Kali is based on these.

it will also run better in a multi-boot or solo boot on your hard-drive, where any distribution can draw on all the resources of your machine

Thanks a lot for your advice.
