Afterwards, it still averages less than 1ms, but we have ping spikes that can show up every 10-90s that can reach up to 80ms. In short though, my main monitoring machine on the network used to have a local ping to both the OPT and WAN interfaces on the netgate box of less than 1ms with virtually no jitter. I do have very extensive PingPlotterPro data that I can post up if need be as well. I do have an old netgate box lying around not in use with an older pfsense plus version, but wanted to at least make a post before ripping apart our edge network cause it is a live production environment. toggling jumbo frames, flow control and all sorts of other settings.disabling HCO, TSO, HLRO and toggling ALTQ.disabling the firewall and NAT completely.approaches for bufferfloat, including limiters and such.wiring directly into the pfsense on a switched port on the WAN block from the monitoring machine.After ruling out many other things on our network, we've been able to narrow it down for certain that it is the 7100 causing the issue, and it start occurring right after the upgrade. Upon the 23.01 upgrade, everything seemed fine at first but we noticed a ton of ping spikes from our main monitoring machine, running PingPlotterPro on around 50 targets, internally and externally. Decided to do a network wide upgrade about a month back and made the jump from v21 to v23.01 (and now upgraded to 23.05 RC). Recent box is a 7100 which has had been runnning on pfsense plus 21.xx for just under 3 years. Been running netgate gear for years for a fiber transit WAN router, and has always been excellent.
