[SOLVED 🤦♀] Slow connections through pfSense
-
Hi, I've been using pfSense for many years; up until recently, on an Intel D2500CCE system. I just recently upgraded my cable internet connection to gigabit, and also upgraded my router to an i3-7100 with 8GB RAM and a 256GB SSD.
For some reason, when I do the speed test from my computer directly to the modem, I get the ~940mbps expected. However, when doing the speed test through the pfSense router, I'm only getting 90-95mbps. Thoughts on why I'd be getting this? Both my PC and pfSense claim they're connected at 1000mbps (so I know the connection between them didn't somehow get negotiated or throttled down to 100mbps)... so I'm a bit frustrated and confused.

@Doktor-Jones said in Slow connections through pfSense:
Both my PC and pfSense
Is here a switch between these two ?
And what about a speedtest from pfSense ?
MTU issues ?
Hardware offloading ? -
Sure seems like something linked at 100Mb. Yeah a test from the firewall itself will show you which side it limiting.
A i3-7100 will be barely noticing 100Mbps.

I feel really, really dumb.
Apparently I'd set up a limiter once upon a time, and while it was initially attached to something specific, I guess at some point when I was "cleaning up" it got detached and just became a floating rule. I disabled all my limiters and bam, computer tested at 933mbps

Ha, that's very easy to do especially on firewalls used for any sort of testing. I've done exactly that to myself more times than I care to admit.

Yeah what confused me the most is that router->internet was testing at 750mbps+ with speedtest-cli, and desktop to router (through the same switch I'm normally connected through) was testing at 400+mbps (when downloading a dummy 1GB zip file I put in the web dir on the router... and it probably could have ramped up faster if it hadn't yanked the entire file in ~20 seconds).
That's what got me looking at the router configuration itself, because obviously the router->internet connection was fine, and the PC->router connection was fine -- so it had to be something on the router itself that was bottlenecking things.
