[cisco-voip] Does ESXi 5.1 still need disable Large Receive Off-load (LRO)? -jason

[Erich Novak]

basically it was a vmware bug :

with ESXi 5.0 I've had no performance issues on UC apps so far, but for peace of mind I still disable it…

What I've heard (and I think it is getting pushed to the wiki soon) is it's specific to CUCM 8.0 and 8.5, but not 8.6+. So ESXi 4.1+ on 8.0 or 8.5 CUCM needs to turn off LRO.  I believe it's related to the RHEL upgrade associated with 8.6.  Unsure on other apps. I would probably turn it off since it's unlikely to cause performance gains for UC apps anyway.

According to the UC on UCS wiki yes.
