Ping spikes on new install

NaterGator

Are you using any of the altq traffic shapers?

Are you using any of the altq traffic shapers?

Everything is unchecked in firewall-> traffic shaper. I am using a completely out of the box install here with WAN and LAN configured.
Thank you

nazuro

Fresh install 2.4.2. Only config is LAN/WAN ports and:
Everything is unchecked in firewall-> traffic shaper->By interface
All three Hardware Offloading settings are Disabled
Added the following to /boot/loader.conf.local:
net.isr.maxthreads=1
hw.igb.num_queues=1
machdep.hyperthreading_allowed="0"
powerd is not running
BIOS: CPU C States Support = Disabled

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!

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 :(

@nazuro:

Hi all, this is my first pfSense build and have noticed some issues with ping spikes while gaming. The issue is not severe - it seems that I have random ping spikes (around three in my last test of 100 pings to 8.8.8.8 ). The latency will be around 24 or 25 and then will shoot up to the hundreds or even 200 ms then go straight back down again.

Hi,

Delayed answer, but in case someone else is struckling with same problem…

I had exactly same issue for months, and tried to find cause from every component in network. Yet it was my pfsense hardware afterall.

Solution:
disable 'Monitor M-Wait' in bios
Could be under Features tab > CPU Configuration

At least work with my Zotac Ci-327
