Iperf on Wan poor performance
-
Hi everyone!
I installed Iperf on pfsense and I ran a test through one device from the LAN to the Firewall and another test through one device from the WAN to the firewall.
The results from the LAN are correct, I get around 900Mbit/s.
The results form the WAN are very poor, I get around 47Mbit/s.On the Firewall side there's a symmetric 600Mbit/s fiber line.
On the WAN device side there's a symmetric 300Mbit/s fiber line.
The hardware running pfsense is a Super Micro XG-1537.
The CPU load is only 1%.
I ran a speed test via py37-speedtest-cli from the Firewall and I got around 585Mbit/s symmetrically.Do you have any idea why this is happening?
Any help will be very appreciated.

you should test from one device on the wan to one device to the Lan (and vice versa) and not to pfSense.
pfSense is a firewall/route and not optimized to work as a clientsystem/advanced/networking
Disable hardware checksum offload
Disable hardware TCP segmentation offload
Disable Hardware Large Receive Offloading
reboot and try againany additional package like ntopng / darkstat / suricata / snort ?
