Hi Everyone,

Just to let everyone know of my experience of network speed on pfsense HVM.

Initially, I started off by doing PCI passthrough for my WAN NIC, and used e1000 emulation for LAN. Speed was capping at 90Mbp/s.

When both were set to e1000, speed was capping at 30Mbp/s

When LAN was set to e1000 and WAN was set to default (rl8xxx), speed was capping at 71Mbp/s.

I wish I could have stayed with the first option, however my link speed is only detected at 10Mbps unless I take the cable out and in 2 or 3 times.

Any tips on the above? In some cases, to get the above speed, I had to enable "device polling" in pfsense

Just an update on the above...

I updated to the latest 2.0-BETA2 version of pfsense and that has seemed to have solved my link rate issue. Using e1000 for the LAN interface, and PCI passthrough for the WAN, the system caps out at around 110Mbp/s, which is good (and acceptable for me, as my colo's internet connection will be 100Mbp/s).

One thing I did note however, was that it only worked this well when there was only 1 vcpu in the guest....

Can anybody explain this behaviour?
