If the LOCAL-ROUTER machine is fast enough, and the cipher selection really doesn't make a difference, is there more to tweak here? 18M->15.5M is ~ a 14% slowdown. I don't know if that's as good as it gets or if more can be done. I've read about IPSEC being 'faster' than OpenVpn but then there's a lot of disagreement on that too. Plus the fact that I have even LESS of a clue about IPSEC :-/ I guess if there was hardware encryption in the loop, probably needed on both ends?, then that may improve. 14% slower isn't horrible at all. But if you can get it to half that, why not? Is there still room to improve here? - John ------------------------------------------------------------------------------ _______________________________________________ Openvpn-users mailing list Openvpn-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/openvpn-users
