Pfsense is slowing my internet down

tman904

It may be the PF(Packet Filter) firewall inside of pfSense causing it. I remember reading that using a stateful firewall can slow down throughput vs a pure stateless router. Although Netgates appliances can route and firewall at speeds much higher than 80mbps.

What is the CPU usage on your pfSense while performing the speed test?

I know you said you didn't change anything but the LAN IP but just to double check.

Are your CPU/RAM and state table resource usages high?
Are you using any add on packages?
Do you have a lot of firewall rules configured?
Did you change PF(Packet Filters) ruleset optimization setting?
You said you didn't have to forward any ports so did you enable UPNP?

I tried disabling packet filtering but it also disabled NAT which I need since I am coming directly from the ONT.

Not using any add-on packages.

Only firewall rules that are set are whatever the default are.

No, I haven't touched the optimization setting - I'll look into that.

I also did not enable UPNP, so I really do not know how the FIOS router is working for the TVs. It is also connected over coax - so maybe it just needs any internet connection for in/out traffic and then the rest is handled through coax.

Basically this is a fresh install.

What is the best way to monitor system recourses? I was looking at the top output in System Activity.

It basically stays like this the entire time - even when running speed tests.

Thanks for your help with this!

I easily see full speed on my internet 250+mbps using my pfsense box.. Intel(R) Celeron(R) CPU G1820 @ 2.70GHz

Id be more interested in what the actual motherboard and ethernet options are..

@jakehaas Are you using the onboard ethernet nic? If so its driver may having very poor hardware interrupt handling, meaning that NIC can slow the system down a tremendous amount. When higher speeds/throughput are pushed through it.

ssh or console in and run "systat vmstat" Then keep that command running while running your speed test. If the Interrupt CPU usage is high and the amount left idle is low that could confirm what the problem is.

Here's my firewall with no problems as a baseline.

60Mbps is woefully bad on that hardware. There is something significantly wrong.

Check the Status > Interfaces page for errors/collisions.

What NICs do you have there? Dell Broadcom multiport cards? bgeX?

Seriously slow. I get 300/25 with the tiny VM in my sig on a 12 year old PC.
Try changing cables and switch ports first, then a new/used i345/i350 NIC if no help.

Did I miss- what NICs you have... STATUS/INTERFACES - verify the WAN mtu is in the neighborhood of 1500 and media is 1000 T FULL. Can't hurt to check all INTERFACES. If it's coming up 100 you aren't going to get faster than that...

@jakehaas said in Pfsense is slowing my internet down:

dell r210 ii.

I've got a feeling they are broadcom based on that machines specs.
Taken from here:
https://www.dell.com/tc/business/p/poweredge-r210-2/pd
Network Controller
-One Dual port Broadcom BCM 5716

I've personally had horrible performance with broadcom in the past. Now I use intel based gig nics.

stephenw10

Most Broadcom NICs should be fine in pfSense but if you are seeing issue check the tuning guide options:

@stephenw10 I was referring to the fact his hardware has broadcom NICs in order to rule those out as a possible problem maybe he should try other NICs,

I personally haven't had those type of driver interrupt problems in years.

stephenw10

Nope me either. I would not expect to see any issues with Broadcom in most setups.

The 60Mbps the OP is seeing here is so low it must be something pretty fundamental like the NICs linked at half duplex or a bad cable etc.

@stephenw10 Could be a fault with the switch it's connected to as well.
