Poor performance with pfsense

mirmit

Hi,

I have a network with a modem/router connecting the wan to pfsense.

When I plug a computer on the WAN router and do a transfert with pfsense also pluged in, I get a transfert rate of about 100ko/s to 200ko/s maximum.

If I unplug the pfsense, I can go over 400ko/s.

The wan is supposed to be able to deliver 6556 kbs.

What could cause this?

I end up to this test, as I get verry poor conection bandwith with the current system. It seem the CPU load is around 10% on the appliance.

What kind of installation are you running ?

Bare metal ? Virtualized ?

What version of pfsense is this ?

1.2.3 ? 2.0Beta?

How is the WAN configured ?

Bridged ? Nat'ed ?

Hi,

It's an 1.2.3 running on its own machine.

The wan is NATed. It's has been a pretty straightforward installation.

Pinto? Fiat? Porsche?

What are the specs of your box that you are running pfSense on?

This kind of degradation sounds like maybe an ethernet autonegotiation issue. What do you see if you do 'ifconfig xxx', where xxx is the WAN nic? (the LAN too, I guess, it might be speed issue talking to the pfsense not going upstream.)

Here is the output of the ifconfigs:

The host is a DellGX280 with P4 2.4Ghz with 1G mem.

I think it should be sufficent for the purpose.

How about netstat -I on each interface?

Here the output:

Hmmm, well doesn't look like an ethernet issue :( For your speeds, are you meaing KB/sec (kilobytes?)

mirmit

Yes, it's Kilobytes per seconds.

This catches my eye… Are you forcing this on the computer end?

mirmit

I didn't. I guess it's the Netopia 4541 router on the WAN end which bring this. There is no option in the menus to act on this.
