I have previously complained that VM’s are frequently i/o bound, but I have just discovered that the real cause of the restriction is Windows 10! Unfortunately the ‘cure’ uses software that is usually labelled as potentially unsafe by many AV programs.
If you use the ‘safe’ Windows Process Explorer you will find it possible to temporarily raise the CPU priority for a program but such changes disappear on reboot and do not appear to affect I/O priority.
If you really need to make one program zing, then install ProcessHacker 2 but be careful where you obtain it. I used the software in the project folder on SourceForge.
ProcessHacker enables you to set both the CPU and I/O process priorities, and set them permanently (right-click on the process you want to alter, set the priority and save it to the application. You can set the priority to ‘real-time’ but this risks locking everything else out.
I used it to set VMWare to have high priorities and it now no longer suffers from Windows pre-emptively taking over resources. My VMs now zing along, and it has (temporarily) removed any immediate upgrading desires.
There are numerous reviews by the various AV companies, but it appears that all reports labelling it as malware have been done in error. However this is a potentially dangerous tool to use as setting the wrong process to real time could bork your PC or make it unusable.
