Ineternet speed after the openvpn connection

Hi,
My adsl speed is 4mbps but when I connect the openvpn and do a test (speedtest.net), I get only 1 mbps maximum. There are no other clients connect to the vpn. I am the only client. Then how it happens? How can I rectify this? Please help.
Thank you.

Hello,
Your upstream is between 1 and 1.5 megs, right?

Hi Stephen,
The down speed is 1mbps and up is about 600-700kbps.
Sorry for the late reply.
Thank you.

Your speed tests make sense, then. As your upstream becomes saturated with outbound connection requests, your downstream speeds with stabilize at a speed lower than what you might expect. This can also be affected by the vpn link itself using udp packets which are difficult to optimize (QOS-wise). If you have the inclination and are utilizing an OS that supports such things, you can look into a QOS method called ACK prioritization for the virtual device itself. Personally, the only operating systems I've implemented this on have been BSD/PF-based--I'm sure there are docs somewhere to do the same in Linux.
