Awful pfSense Performance Help
-
Hi everyone -
I am having some very debilitating issues with my pfSense setup. I have a 2.2.1 machine with
- C2D E6550 @ 2.33 GHz, 4GB RAM, a TP-LINK TG-3269 gigabit PCI NIC (LAN), and the onboard gigabit NIC for the WAN - I believe it is Intel
All the box is really doing is DHCP, Squid, and most of the default features on a 60/50 mbit/sec connection. I have two Ubiquiti UAP-LR running on the LAN, and currently, about 30 connections. The APs are load balanced @35 users/AP, and I have set the download limit (for wireless connections) to 3000 kbit/sec. When I ran the iperf test (wired), I repeatedly get:
–----------------------------------------------------------
Client connecting to 10.0.0.1, TCP port 5001
TCP window size: 8.00 KByte (default)[156] local 10.0.0.10 port 61119 connected with 10.0.0.1 port 5001
[ ID] Interval Transfer Bandwidth
[156] 0.0-10.2 sec 5.29 MBytes 4.37 Mbits/secThis is at a time when there is very little activity, and the CPU usage is basically nothing. I am beginning to suspect that the LAN NIC is the culprit, but I am not sure how to tell for sure.
Any ideas? What should I do? THANKS GUYS!

What kind of switch? Does Status > Interfaces show any errors? Does looking at the ethernet counters on the client or the switch ports show any errors?
What kind of iperf numbers do you get running the other way?
iperf -s -u
+
iperf -c server_ip -r -u -b 100m -
First of all, I want to thank you, Derelict, for your help.
No in/out errors or collisions on either interface. Can you please explain this to me: " Does looking at the ethernet counters on the client or the switch ports show any errors?"
What does this information show me, and where can I find it?

On the client and in your switch. No idea what you have or how to access it. Slow throughput in one direction might be an ethernet duplex mismatch. Error counters usually reveal that.

Are you positive you weren't testing through a limiter?

Thank you for your reply, Derelict.
I just want to let you and everyone else know that I replaced the Realtek LAN card with an Intel PT server card, and the problem pretty much went away. Way better performance. Thanks for your help!
