I have also tried with Linux GRE tunnels (ip_gre). The results were the same. The last idea which came to my mind was openvpn. I set up openvpn in bridge mode also on top of IPSec. The results were only a little worse than the third trial. Any suggestions?
No, not yet. We've also seen a bad interaction between IPsec and GRE when it comes to performance. This is something we're planning to investigate in the next few weeks. I'll follow-up on this thread when we know more.
