Ping spikes on WAN and LAN site
i recently upgraded (downgraded) my pfSense box from a Xeon 1220l (Supermicro board) to a Supermicro A2SAV-L with 8 Gigs of RAM.
Everything is working fine except for one thing. I am getting huge ping spikes on both LAN and WAN.
If I ping my pfSense box I am usually getting <1ms, but the ping will rise to ~60-90ms and then drop down to <1ms. Same on the WAN side. Usually I am getting a ping of 19ms, but now it will rise to 100-300ms range and then drop down to 19ms.
The only thing I am running is a OpenVPN client (PIA) for two devices. Even with the VPN turned off the issue persists.
I am using Cloudflare for DNS.
These are my custom options:
server: private-domain: "plex.direct" ssl-upstream: yes forward-zone: name: "." forward-ssl-upstream: yes forward-addr: 188.8.131.52@853 forward-addr: 184.108.40.206@853
(I read somewhere that some of those options are no longer needed, would be nice to know which exact.)
Besides that I only got a port forward setup for my Plex server.
Power saving features are all disabled.
EDIT: I fixed it by resetting my BIOS/ UEFI
Interesting. Do you have any idea what setting in the BIOS may have caused it?
I do recall seeing similar issues with some PCI power saving feature, a loooong time ago though.
I think it is related to the P and C state settings in the BIOS.
It is possible that I changed one of them and just forgot.
P-state is the exact one I changed I think.
It has to be set to its default value (HW_ALL irc).
These may help:
