I am looking for one or possibly more commands, or a combination of commands, to get my PC to use as much resources as possible.
I want to check how my computer behaves when subject to the maximum amount of data it can handle.
I've tried by running multiple programs such as browsers, graphic and system tools one by one and all together, I've also tried to download big files to monitor its network and storage performance but every time depending on what program(s) I run, I get different results in terms of RAM, CPU, I/O.
Often my whole system crashes and I have to reboot or struggle to close some programs. To monitor, I'm using different commands such as
iptraf but also some other little programs. (I'm using ubuntu)
I would very much appreciate an answer that could list some way to exploit GPU, CPU and RAM and a way to write a file (even with zeros) in the quickest way possible to see how fast my computer can produce output and write it on the HDD.
