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=E2=80=99s performance? cheers, dnny
