Achieving 1 Gigabit Speeds with Hyper-V

[Dan1]

Hello,

I'm new to pfSense and have been doing a lot of searching to see if my setup is suitable to take advantage of my Gigabit internet connection.

When speedtesting with a direct Modem to PC connection I receive 850 to 950Mbps
however with pFsense in-between I have never tested over 600Mbps

Here is my setup.

pfSense 2.4.3 virtualized with HyperV
CPU: AMD Phenom II X6 1090T Processor (6 Cores assigned to VM)
Memory: 8GB Total (2GB assigned to VM)
NIC: HP NC364T PCIe 4Pt Gigabit Server Adptr
NIC Config:
1 Port dedicated as External Network Virtual Switch in Hyper-V for WAN
1 Port dedicated as External Network Virtual Switch in Hyper-V for LAN

Originally I was maxing out my speedtests at 500Mbps but after unchecking
Hardware Checksum Offloading, Hardware TCP Segmentation Offloading, Hardware Large Receive Offloading
I was able to achieve 600Mbps

Also running iperf with pfSense as the server mimics the speedtest results.

I feel like my hardware should be sufficient to achieve gigabit speeds and I am just missing some simple configuration.

Any help would be greatly appreciated, Thanks!
