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.
