Very slow internet speed

bossa

Folks,

I've moved my ISP to Comcast to get a faster speed - 1Gbps, bridged the modem and connected my pfSense box to it. All good but the speed.

Via pfSense I get about 150 Mbps, connecting a laptop straight to the modem, I get 800 - 900 Mbps. As I've not yet disconnected the old ISP, I switched the WAN to that modem and got 90 Mbps, wish is fine as it is a 100Mbps service.

I suppose it is a configuration problem, as I use pf on my son's with the Comcast 1Gbps plan and he gets 600 - 700 Mbps on ookla tests.

If someone can help me solving this problem I'd appreciate.

Here's some information about the box:

And by the way, followed: this tutorial

and using this on my /boot/loader.conf.local:

kern.ipc.nmbclusters="1000000"
net.inet.tcp.tso=0
hw.igb.fc_setting=0

Solved. Hardware related.

So what was the problem?

Unsure. That server is a tween server. On the left side ESXi is installed and the right side was not in use, so got pfSense there as needed several NICs for this setup. I think it could be CPU temps getting too high, as every time I saw pfSense showing them in yellow my network was slow. Interesting is that the other motherboard with the same pair of xeons and 24GB running ESXi 24/7, never had a problem.
I can't run tests with that configuration anymore and I didn't get any others suggestions here or on the other two forums I've posted, so replaced the entire box with a spare i5 desktop and it is running very well.
