After a little more investigating we found that the VM setting for synchronizing guest time with host was checked. This is not a setting that we modify on VM guests so I have to assume that it was set in the original VM image we loaded from Solarwinds. I am attaching an image with the setting location. This needs to be unchecked, and then I had to run ntpconfig again from the CLI. Now my time is at least synchronized. I will continue to monitor the performance to see if this resolved the issue. Thanks again for pointing me in the correct direction.
