I have a very similar setup in terms of base technology and I have been through the highs and lows of 10GbE technology with VMWare and DSS.
Testing it with Crystal Disk Mark. And right now just trying a sequential read. This is a VERY long journey starting with OF, and not getting 10GBE to run properly, now moving to a supported platform with even worse performance.

I've now eliminated the switch, and I'm running direct card to card, with the same performance.

I've switched out the NetXen on the ESX side: I'm now running a Chelsio card. Same exact problem.

No load whatsoever. I only have 1 Server 2003 VM, 1 vmdk. This is just to get baseline.
