Hi CPU Usage even at rest

[daivdW2]

Welcome to the forums. Mis dos centavos.

Virtualization is a really complex business, so much that the Oracle product refused to run on my 10-year-old PC.  It doesn't seem to care neither how much RAM is installed. It's recommended to really install Linux Mint or whichever penguin and try again.

Is your processor AMD? Because it seems there are difficulties trying to keep stuff up to date equal to Intel.

It might have to do with Linux kernel as well and other factors. If you insist on virtualization I strongly recommend Fedora or Arch-based OS to test in. IJS, with the equipment you have which could well support a rolling-release distribution.

I have included two graphs below. The first with the larger area is QB64PE running a small program and then sitting in the IDE only.

The second with the smaller area, is the same small program in QB64.

Did you take the screenshots while one of the "INPUT" statements was being executed in your program? Which is this "QB64" that you mean, the "official" one (v2.1) or the "dot-org" one (last was v2.0.2)?

It was the QB64.com version - 2.1 it states on the download page. 

I took the graphs while the IDE was doing nothing other than sitting there with the code in edit mode. It had been run, a few times in fact. But was do nothing in particular at the time. 

I repeated the test on an Ubuntu 22.10 and got the following results - this time I also paid attention to the memory.

On this occasion the CPU ran to about 60% but almost the entire 4GB of ram was used. 

I will try to find the time today to repeat this test on 'real' computers running the same OS's
