more cores slower optimisation

Postby kagein » 13 Apr 2020

I've got two servers, one running AMD TR 1950x 16 core and the other AMD TR 2990WX 32 core. When i run the same optimisation with the same data (using all threads) on both machines, the 16 core machine always finishes first. The TR 1950 seems to be using 100% of the cpu during optimisations whereas the TR 2990wx rarely uses more than 60%. I've attached screenshots of the task manager from both servers. Any ideas on how i can get the 2990wx cpu utilisation up to 100%.

Thanks

There could be an issue with how the 2990wx is configured in the bios. When i get access to the server and can update the bios, ill run the test again and report back.
