    Performance problems with a simple openvpn setup

    How do go about discovering where your bottleneck is with an openvpn setup?

    Ive setup openvpn on my remote server and have setup everything so that my desktop clients (vista and ubuntu) at home can connect and have all internet traffic directed successfully through the tunnel.

    Im using it to stream video that would normally be inaccessible outside of the UK whilst im in Japan i.e. iplayer.

    The problem is its oftenvery choppy and unplayable. Though its good when england is sleeping.

    Im new to servers (not to stuff like programming though) so dont know where the problem lies, how to find it out or even where to start looking. For example things ging through my head

    Is it the limitations of the vps? How do i find that out? my plan:- vps1
    Is it the location of the actual server in the uk? How do i know if there are any better coming from japan?
    Is it my configurations? How do i pinpoint that?
    Or is it working as good as it can be? How do i know that for sure?
    etc etc

    What would be your process of elimantion? Quick checks that would tell you which direction to move forward in?

    Install the following:

    * iptraf - show bandwidth utilization
    * iotop - show hard disk utilisation
    * htop - show cpu utilization

    It might be easier to just install Munin and let it generate pretty graphs for you

    This is caused by Internet congestion. Either the BBC is having a problem, or your VPS provider is having a problem, or your ISP in Japan is having a problem.

    Possibly....depends who your host is IMO

    Well, the first thing I would do is get a VPS from another provider and see if it has similar issues....

    If all you need is a VPN however you might look into companies specifically selling VPN services.....it will most likely be better than what you can achieve with a VPS - and cost less too

    We have plenty of customers using OpenVPN without an issue, in fact. I would recommend you lodging in a support ticket so we can look into this.

    Thank you.
