ix(intel) vs mlxen(mellanox) 10Gb performance

[Daniel Braniss]

hi,
	I have a host (Dell R730) with both cards, connected to an HP8200 switch at 10Gb.
	when writing to the same storage (netapp) this is what I get:
		ix0:		~130MGB/s
		mlxen0	~330MGB/s
	this is via nfs/tcpv3

	I can get similar (bad) performance with the mellanox if I increase the file size
	to 512MGB.
	so at face value, it seems the mlxen does a better use of resources than the intel.
	Any ideas how to improve ix/intel’s performance?

	cheers,
