Painfully Slow Centos/RHEL Linux Performance on Workstation 15.5.2 Pro

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!

Sort of the same issue here.

I loaded 15.5.5 on CentOS7 but this version of WS did not support my (AMD Opteron) hardware, which is considerably different than yours.

Ended up loading 15.5.2 that does run the VMs coming from WS 12 on this hardware.

The network performance is terrible to the point of really not functional after a little bit of time running.

High CPU on the Linux VM acting as a firewall.  Switching this VM between CentOS 8 and 7 no change.

I am in the middle of downloading and going back to Workstation 12.5.9.
