Subject: Re: Reduce CPU load. Is it possible?


I have a laptop working 24 hours a day. It is a Bitcoin node and also has a
small ASIC-USB working as a miner.

Now, he also has John the Ripper running trying to decrypt some Bitcoin

Of course I am interested in maximum power, but I do not want to reduce the
life of the processor, it is working without too many expectations of
obtaining any result with John the Ripper.

That is why I wanted to offload the CPU work a bit. (80% would be fine).

What is your opinion?

A greeting.
