speaking of ipv6 - can anyone do an iperf via ipv6 from their ARP VPS etc to something remote ?
im testing with iperf3 - and i get single digit mbit/sec :(
multiple destinations (tested spectrum CM, VZW)
ipv4 zips right along though at the expected speed
20 Mbits/sec up/down over my IPv6 tunnel, 100 Mbits/sec up/down over v4. I'd blame the tunnel for the discrepancy. I'm on FiOS (so no native v6).
yeah im testing all native...
just tried another - gig connected bare metal in cyrusone (as62) - 2mbit v6 / 350mbit v4 :(
in all 3 cases - my path from ARP to the test destination includes he.net....
Huh. My tunnel is HE.net and it's fine. Wonder what's up there.
it almost feels like something in the path is software forwarding
i would think if thats the case the cpu would be pegged on that box causing other issues though (bgp session drop etc)
