Hi Folks,I have parsed around a bit but have not come up with a solid suggestion to increase performance in the following environment :
. +150 clients always on, always via COAX modem 15Mb/s down 1.5Mb/s up. . OpenVPN-2.0.9 and 2.1rc13 tested, setup as single server . Server Kernel 2.6.25.4 . Server 64bit . Server CPU % rarely goes above 30 . Server is fed over a 10G linkCurrently we get what appears to be only between 5 and 6 MB/s average using this setup.
If only activity is over a single tunnel we can get the expected max (about 14Mb/s to the remote site) for the COAX sites. Once traffic builds during the day, that number drops.
We know if we hit it locally we can get 160Mb/s. We know if we do hit it locally and are getting the 160Mb/s that the COAX tunnels do suffer. Starting by almost 1/2 of their normal throughput tunnel speed of almost 14Mb/s.
So in my small mind, I am thinking we are seeing around 48Mb/s (6MB/s*8) used, but that we should be able to get over 150Mb/s. CPU isn't hurting. Almost feels like there is a governor slowing down the traffic :).
Important settings from latest config : verb 1 dev tap tun-mtu 1500 tun-mtu-extra 32 mssfix 1468 proto udp ca SSCert.pem cert servercert.pem key serverkey.pem dh dh1024.pem tls-auth ./tlspass keepalive 30 63 ping-timer-rem persist-tun 1 persist-key 1 cipher none tcp-queue-limit 4096 sndbuf 131072 rcvbuf 131072 Anyone have any words of wisdom :) ? Thanks, JES
