Hi,
I use two mikrotik devices with two tunnel brokers separately. The IPv4 bandwith between two routers is about 70Mbps, and the ping is 100ms.
The throughput test results are confusing.
| One TCP connection | 20 TCP connections |
IPv4 directly | 10Mbps | 70Mbps |
IPv6 tunnel (he.net, IP proto 41) | 200Kbps | 2Mbps |
EoIPv6 tunnel (IP proto 97) in IPv6 tunnel (he.net, IP proto 41) | 9Mbps | 70Mbps |
The throughput of each TCP connection in IPv6 tunnel is very poor. Using another IP protocol (e.g. 97) can make it faster.
Is there any restriction in he.net IPv6 tunnel broker?
I have no idea on it, but I also get very poor performance these two days using Hong Kong server. Also Unstable ping.
