Slow IPv6 transfer speeds

Hi,

I have a couple of Ubuntu boxes on my network. When I use IPv4 for file transfers, I get around 200MB/s, which is ok. But when doing the same file transfer over IPv6, I only get around 1-2MB/s. Has anyone experienced something similar? And does anyone have a suggestion on what could be the problem?

Below is the the transfer via IPv4:

Code:

jonas@calculon:~$ scp 1Gfile.bin  [email protected]:/dev/null
[email protected]'s password:
1Gfile.bin                                    100% 1024MB 204.8MB/s   00:05

... and IPv6 (I used a 200MB file instead of a 1G file):

Code:

jonas@calculon:~$ scp -6 200MB.bin jonas@[2a00:xx::y]:/dev/null
jonas@2a00:xx::y's password:
200MB.bin                                      10% 2336KB   1.0MB/s   00:19 ETA^C

Thanks,

BR Jonas
