I ran into this one a while back where CentOS 5.x used to be slow on VM
running through the network bridge. The fix at the time was to issue an :
ethtool -K eth0 tso off. So i did just that and here are my current
# ethtool -k eth0
Offload parameters for eth0:
Now this unfortunately does not work anymore. I have searched a few forums
and no one seems to have run into that one.
Here are the speeds compared on v4 and v6 (this is from HEAnet's mirror)
wget -O /dev/null -c

Tested this several times over, this is giving me the same results. If I
disable the bridging mode on the network card, i get full speed over IPv6.
Step by Step, the penguins are taking my sanity away.
