So having read all this, the only thing I can think of is the ethernet port on your ISP router maybe?

i.e. when you test from your ISP router, are you testing from a device plugged into it, or from it directly?

What I mean is that running a ping on the router itself might be telling you "the router is fine" when actually if there's a problem with the router that causes latency/issues only on it's "LAN" port (the port you plug your pfSense into) you won't see it.

What if you plug a laptop into the TeamTalk device and test using it?  Does that show you the latency spikes?

Also, what if you remove "the internet" from the equation and configure two laptops.  One pretends to be the Internet and one is a LAN client, then you ping between the laptops via the pfsense (you'll need two NICs on your pfSense box)

Does that show you latency?

Hi muppet, thanks for your time. I did come to the same thought but unfortunately disproved it by:
  • Plugging Windows laptop into TalkTalk Router directly, and pings were fine
  • I also have latency on the LAN
  • Running FreeBSD on the server seems to work fine regarding latency

So even ping between two laptops, via pfSense, shows the problem?

Can you post the output of dmesg? I'm not a FreeBSD guru, but maybe we can spot something in there that might be the cause of the problems.

Unfortunately so :( and strange that FreeBSD live USB didn't have the problems! Must be some sort of setting in PfSense

Me neither re FreeBSD guru but I thank you for having a skim over incase!
Here's the output https://pastebin.com/3wCFpKqW

I'm completely lost for ideas now, may have to scrap pfSense and go back to DD-WRT :'( Or at least buy a new motherboard/processor combination...

Any suggestions for ITX motherboard/CPU that has AES-NI and a proven record of being good for pfSense? Or alternatively any other troubleshooting options to test the LAN/WAN latency issues

I've also tried setting the Cryptographic Hardware from BSD Crypto Device to None, to no avail :(
Thank you all

Maybe try disabling MSX-I and/or Flow Control?

https://doc.pfsense.org/index.php/Tuning_and_Troubleshooting_Network_Cards

Also try running using a RAM disk (System->Advanced->Misc), maybe your pfSense writing logs to disk causes the system to pause/freeze up for a moment?

These are all just stab-in-dark guesses now :(
