Hi all,

Customer wants to know where do you set the NFS TCP Receive Window Size in ESX?   Any recommended value for 10Gigabit Ethernet on a Cisco Nexus (low latency switch)?    Latency is 0.025 ms.

Setting should be under Host-->Configuration-->Advanced Settings-->NFS

And....if you install the ESX Host Utilities a good bit of that stuff will get auto-optimized (HU are really a necessity on any server connecting to a NetApp).

TR-3428 also gives some of the esxcfg-advcg command syntax which can be handy for rolling out manual changes quickly/scripting them.
