Hi all,
I have set up over last day two separate tunnels on tunnelbroker.net. Two different accounts but same server location.
One router with tunnel working on Fibre (FTTP) 100/100 connection and operated via Draytek 2860n
Second router is WRT3200ACM with OpenWRT and connection from Virgin Media 100/10.
Bot connection. Reaching their Download speeds on IPv4. Virgin is even faster.
I set tunnels on both and start testing speed when connected to IPv6 network.
Firstly I thought that due to tunnel the speeds will be slower, but than start comparing.
Draytek on download IPv6 have roughly 86-96Mbps.
OpenWRT on download IPv6 have roughly 6-10Mbps (!!!).
Huge difference.
I know that Draytek is not using OpenWRT but that’s 2012 moder hardware was hi-end Linksys.
Wonder if somebody can advise where to look on improvement, as 10% of original download speed not allow me to use IPv6 daily.
It looks more like some software/hardware incompatibility or settings difference.
Tried MTU change from default 1280 up and down but no speed difference CS.
How is the CPU utilization when you download something?
0.07 on IPv4
0.16 when adding IPv6 and testing speed
Hence no big difference.
Saw a thread here
And here
But nothing help.
