Where do you set NFS TCP Recv Window Size in ESX?

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.
