Network issues after upgrade to 6.5

I recently upgraded my environment to 6.5 from 5.5.  After a few hiccups related to non-standard ports, I was able to deploy the VCSA and subsequently upgrade my hosts.  Now I am seeing some unusual network behavior.  I was upgrading to distributed virtual switches over the standard switches.  When I would perform the changeover, I noticed the ping time from any of my hosted nodes increased significantly.  Average times went from .3ms to over 1.5ms.  Swapping back to the standard switch resulted in the lower ping times I expected.  Any hints to help me troubleshoot this issue?

If you have upgraded the host also, please verify if you are running on supported nic driver/FW.
