      Recently, I've been having intermittent lag when accessing the internet. After doing some investigating, I discovered that the latency on my WAN is very high (400ms+) and sporadic. I have attempted the following fixes:

      • Rebooted ESXI, PfSense, and my modem
      • Updated PfSense to the latest release (2.4.4-RELEASE-p3)
      • Disabled Gateway monitoring & action (as the sporadic jumps in my WAN simply resets my GW)
      • Implemented QOS (CoDel) @80% of the DL & UL speeds as per my internet package (just in case BufferBloat was the cause)
      • Contacted my ISP and had a tech come out. He replaced the modem.

      Unfortunately, none of these fixes solved my issue. Any advice?

      Background info:

      • Pfsense is running on ESXI (ver 6.7) on an R710 with Broadcom NICs (NetXtreme II 5709)
      • Assigned 1 vCpu & 2 GB Ram. CPU and mem usage are around 10%
      • Networking setup is Modem > PfSense WAN > PfSense LAN > Switch > devices
      • My current setup has been running for over a year with no issues

      1 week of WAN monitoring
      1 Week Wan Monitoring

      1 month of WAN monitoring
      1 Month WAN Monitoring

      Any help would be greatly appreciated.
