ST running in VM shows constantly high CPU load

[decay]

Hi Ivo,

not sure if it’s of any relevance, I just wanted to report:

As I wanted to do a side-by-side comparison of SVDevon version 1.8 and 1.9, I tried to run one ST instance on a virtual Linux machine. But that doesn’t seem to work. ST starts up, but it constantly eats up about 20% of CPU load, right after start, while doing nothing (ST itself idle / no image loaded). I’ve no idea, what’s going on there, maybe a problem with (failing) memory allocation?

What you can see: Oracle VirtualBox running Linux Mint on my Windows notebook. ST 9 running in that Linux VM. ‘Top’ is showing that ST uses 21% CPU load. Windows Task-Manager is shown as window on top.

But as said, that’s probably irrelevant as it usually doesn’t make any sense to run ST inside of a VM ...

Best regards, Dietmar.

Hi Dietmar,

Some usage by the UI thread (and any OS functions that are spawned by it such as file dialogs) is expected, which all happens on a single thread.
How many cores did you allocate to the VM?

Thanks Ivo! It was only one lonely single CPU core and now with two it works fine!

It was much more than that - one of the 4 'physical' cores was completely busy and the fan raised up. Something seems to go wrong if only one core is available. But I learned that the last single core desktop CPU was produced in 2013, so this discussion is just waste of time

Thanks again, Dietmar.
