I see I have old sysctl.conf settings here, from tuning way back in the 2.6
era:

  net/core/rmem_max = 8738140
  net/core/wmem_max = 8738140
  
  net/ipv4/tcp_rmem = 4096 873814 8738140
  net/ipv4/tcp_wmem = 4096 873814 8738140

Perhaps it's time to kill them, but I don't know what the defaults are :-)

35.7–36.0 ms.
