Slow LAN and WAN throughput in ESXi 6.0
-
Hello!
I have problems with slow WAN and LAN Connections if I use my pfsense as a router. Usually I have 150/10Mbit Connection. If I use pfsense as gateway it goes down to 50-70 Mbit/s download and 10 Mbit/s Upload. If I use the fritzbox as gateway I'll get fullspeed.I followed this guide to set pfSense up: https://snowulf.com/2015/08/31/tutorial-using-vmware-esxi-and-pfsense-as-a-network-firewallrouter/
pfSense is running in ESXi 6.0 with a bridged fritzbox 6490. The machine has 3 GB RAM and two CPU virtual sockets with two cores. The NIC is a HP NC364T, 4x 1000Base-T, PCIe x4 (http://www8.hp.com/h20195/v2/GetPDF.aspx/c04118440.pdf)I changed all network cards to VMXNET3 and reconfigured them. Unfortunately it didn't help :( The speed is stuck at 70 Mbit/s.
Yesterday I also reinstalled the latest version and installed just openvm-tools. The speed is still around 70 Mbit/s while direct connection to the fritzbox gives me 150 Mbit/s.I also measured the speed between the two computers in LAN using iperf. If I'm using the pfSense as gateway I'll get only ~500 Mbit/s. Using the fritzbox gives me ~980 Mbit/s.
Always when the pfSense is involved the speed falls in WAN and LAN. I have really no idea what more to look for, as the CPU and RAM are not overloaded (they aren't under load anyway)

Any help is appreciated! Thank you very much!

"I also measured the speed between the two computers in LAN using iperf."
What would pfsense or even esxi have to do with tests between 2 computers on lan?? What is the switch that connects these 2 computers you tested with? Why don't you draw up your network.
Also I have seen isp that when they see a new mac, ie your pfsense wan connected to your router not have that new mac provisioned for full speed - that is long shot… But why don't you test what your pfsense vm can route/nat speeds at by placing a box one wan side and box on lan side and testing between them..

Thank you for your reply!
You brought me on the right way. The problem is a bugged firmware in the fritzbox when you used a bridged port. I changed it for a modem and the problem is gone. :) -
But again that would have nothing to do with speed between 2 machines on the lan.. Unless they were maybe using ports on this fritzbox as their switch??

Yes you are right. I should have mentioned that the measurement was between two VLANs.
Now the problems are gone and I'm happy with my pfsense :)
Thank you again to bring me to the right way!
