I have often seen that running "just iperf" will produce wildly varying results, both on Ethernet and VPN links. Hi, I with this options, I have 94M outside of the VPN and 87.8M inside with a 2.3.4 server and a 2.4.3 client. So, it looks like pretty the same than without the options. so the good news is that the numbers are now more or less constant, right? And if your outside LAN speed is 94 Mbps then I am not surprised that both the 2.3.4 and 2.4.3 client max out at ~ 87.8M - that is close to the maximum of what you can get out of an OpenVPN link over such a network. Still, I would have expected 87.9M for 2.4.3 and 87.7M for the 2.3.4 client ;) cheers, JJK -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ___ Openvpn-users mailing list Openvpn-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/openvpn-users

Yes, it’s across Internet but the link was pretty unused when I did the tests (I rerouted the rest of the traffic on another link). I just rerun a test to the router outside of the tunnel, and I get 93.0 Mbits/sec without rerouting the traffic. -- alarig signature.asc Description: PGP signature -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot___ Openvpn-users mailing list Openvpn-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/openvpn-users

Is there anything in between these systems? Was this across the Internet or just on the local network?
