Project report running very slow on Windows 2019 server whilst ok on Windows 10 machine

Hi,
we have a customer who is running project activity report "PJACT" which takes 5 hours directly on a server and about 45 minutes if ran on the local machine.
The server is Windows 2019 server (virtual Machine) taking 5 hours whilst the local desktop is Windows 10 machine. What do we need to do on the Windows 2019 server to make this report run at the same speed as the windows 10 machine ?

Kind Regards

Pradip
