Dear all,

I have a computer with an AMD EPYC 7251 dual boot between windows 10 and Ubuntu 16.04. When using an application, it is almost 1.7 slower on windows than on linux OS. I made the test with another CPU (Intel Xeon X5690) even if the performances are much lower than the AMD EPYC 7251, I do not have this discrepancy between linux and windows OS. I have read that the AMD PSP is not fully supported on Ubuntu 16.04. Could it be the origin of this discrepancy? Is there a way to improve the performances on windows (either at the level of the OS or at the level of the application). Thank you.

Best regards,
