   Hello Brian,   
      
   On Wednesday September 15 2021 11:30, you wrote to me:

   Sure. The frustrating part is that I was never able to figure out what it was.   
      
    BR>  Granted the MTU is slightly and I mean slightly less than native   
    BR> IPv6 or IPv4, but it's only by 20 bytes/1500 byte packet. Doing the   
    BR> math, this does NOT equal a 50% lag.   
      
   Indeed, so it is not that.   
      
    BR> Maybe the issue is that your ISP's path to your IPv6 tunnel provider   
    BR> is not an optimum path? Mine is just a couple hops away so it's not an

   Unlikely. I used the the he.net POP in Amsterdam, no-one in The Netherlands is   
   more than a couple of hops from AMS-IX.   
      
   The prime suspect is still the router that ran my tunnel endpoint back than. A   
   Linksys WRT54G running OpenWrt. But I could bever make sure.   
      
   Now it is irrelevent, I now have native IPv6 and I see no significant   
   difference in pefomance between IPv6 and IPv4.   
      
   Cheers, Michiel
