      I have a small, simple network with a Netgate SG-2100 running the latest pfSense version.

      Internet > Comcast Cable Modem > Netgate SG-2100

      All the computers are behind the SG-2100.

      The client was complaining that the workstations seemed slow, with no real further explanation.

      My first check is always DNS and I found this...

      C:>nslookup yahoo.com
      Server: one.one.one.one
      Address: 1.1.1.1

      DNS request timed out.
      timeout was 2 seconds.

      Non-authoritative answer:
      Name: yahoo.com
      Addresses: 2001:4998:24:120d::1:1
      2001:4998:44:3507::8001
      2001:4998:44:3507::8000
      2001:4998:124:1507::f000
      2001:4998:24:120d::1:0
      2001:4998:124:1507::f001
      98.137.11.164
      74.6.143.25
      74.6.143.26
      74.6.231.20
      74.6.231.21
      98.137.11.163

      This happens no matter what DNS server I use, and no matter what domain name I look up- there are always two timeouts followed by a valid DNS lookup.

      Any ideas on how to troubleshoot this? I have a similar configuration at several other clients and this does not happen.

        What do you see from Diag > DNS Lookup in pfSense?

        Are the clients using 1.1.1.1 dircetly for normal lookups?
