ESXi 5.1, Dell R720 and Intel I350 Network Cards

Hi,

We are encountering some serious performance issues running running UTM 9.0 on a Dell R720 with ESXi 5.1. The network cards in the machine are all Intel I350 Quad-port 1GB adapters.

The throughput from the adapters is approximately only 200 Mbit instead of 1 Gb.

Is anyone else using a similar configuration and encountering performance issues?

If so have you been able to solve it and how?
