OpenVPN Support Forum

Hello,

I am again with a new problem regarding speed

OpenVPN TAP interface showing 10Mb connection, what does it mean?
Can we forced openVPN TAP to use fully LAN card available speed to give connected VPN session?

Jebran.

Hello Douglas,

Thanks for advise, if the 10mbps are bogus number so kindly advise what possible factor can affect speed of OpenVPN clients.

I have tested from many ways, MS RRAS also configured on same server , I have dial PPTP,L2TP to this server test internet speed awesome through it.
Please advise.

Cpu can be a limiter if you are using it on say, a raspberry pi. Your connection to the actual vpn can affect speed too.

CPU almost free at server side.

Your connection to the actual vpn can affect speed too.

When I try to download a file through PPTP speed was "2.8 or 2.5MB/sec" but when i tried the same thing from same location via OpenVPN speed was 190.4 or 184KB/sec it is big difference.

Dear Michael & Douglas,

To observe the speed issue I have found error on log "write TCPv4_SERVER: Connection reset by peer (WSAECONNRESET) (code=10054)"

Please advise possible reasons as well as best combination of MTU for windows.

Had almost the same issue. Fixed by:

sndbuf 200000
rcvbuf 200000

Hello lukit,

Thanks for the suggestion,

sndbuf 200000
rcvbuf 200000

You add only server side or both side? I fixed it by change server listening port TCP to UDP.
