How to increace the data transfer rate in openvpn

[Sreejith P]

Hi ,

I have a large number of servers set in amazon and they are connected via openvpn so that i can access my home destop also. I found that the data transfer rate is very low about 5MBps ( the data transfering is done via openvpn ) . I wonder if there is any way to rise this data transfer rate to some high value about 20MBps. Can you please help to raise this data transfer rate? Please find the server.conf and client.ovpn shown below :

try adding

Code: Select all

tcp-nodelay

on the server; you can also try playing with

Code: Select all

mssfix 1400

or try lowering the MTU size of the tap adapters on both ends.
