I recently upgraded my VMware Workstation Pro from 13.x to 15.5.2 and I have noticed a dramatic drop in performance of Linux (Centos 7and RHEL 7.x) VMs that I have been building as compare to previous VMware releases. The OS installation goes well, per VMware recommendations I have been using open-vm-tools instead of manually installing the vmware-tools. As part of my job I depend on testing several java applications which run as services, these are very light weight and previously started in a matter of seconds. Now they take 10-15 minutes or more to fully start, I can't even get jboss to finish deploying a war file before timing out (deployment timeout is set to over 10200 seconds). While installing one of the products I have to test it copies numerous XML files from a source directory to an installation directory, this should be extremely fast but is taking over a minute and a half per file. A product install that would normally take under an hour is take 16 plus hours. During any of the above if I use top/atop/htop it shows virtually no load on the system at all. I have tried multiple versions of Java as well to no avail.
The VM has allocated:
2 vCPU Intel i7-6820HQ 2.7GHz
6 GB of RAM
Plenty of disk (SSD) and no swapping is going on. The rest of the workstation resources are idle as well so there should not be any resource contention.
I am at wits end with this issue and I welcome any suggestions!
