You really need AT LEAST 1 Gbps physical network for it to be worthwhile. I’ve seen it literally make a 100% difference in performance. The faster the physical layer the more difference it can make…
Of course, going from SMB1 to SMB3.x can do the same.

And nobody really knew about it when I asked. The few 2008 servers I've checked have it turned on, which is default. This will be something I revisit once VMware fixes the current issue. Look forward to testing on a few servers to see if there's a noticeable difference.

That's okay, got it anyway. Both points are very relevant to me and I've passed on the information about the packet loss to the rest of my group, as I didn't know about this until you posted here. If I check a Windows 2012 VM that is current with its Tools on a 5.5 host, it's at the latest unaffected version. We are just adding 6.0 hosts and I suspect that if I were to upgrade any VMs on those hosts, they would be at an affected version, so I've let everyone know to hold off until there is a patch. Thanks again for the information. -----Original Message----- From: [email protected]<mailto:[email protected]> [mailto:[email protected]<mailto:[email protected]>] On Behalf Of Kurt Buff Sent: Monday, March 27, 2017 5:41 PM To: ntsysadm <[email protected]<mailto:[email protected]>> Subject: Re: [NTSysADM] Anyone see this VMware announcement and deal with it? Dang it... I forgot to put in the point of the post: Win2012 and Win2012R2 machines with current-ish VMware tools and RSS enabled can experience some packet loss. Current recommendation until VMware fixes the VMWare Tools is to older version. Yuck.
