[Openvpn-users] Re: Openvpn slow on asymmetric connections

[George Thompson <kizaki.ovpn@xxxxxxxxx>]

Hey there,
My laptop harddrive just died.  I am now using Knoppix Linux from a CD
to use my computer.  I installed Openvpn and connected to my server. 
Now that I am using Linux I am getting the full speed.  I am now
getting around 14.2 mbits/s down and 1.7 mbits/s up though the tunnel.
 I am assuming this is a Windows issue.  I tried openvpn on my
brothers computer.  He has Windows Xp and it was running slow.  But
when I booted up Linux on his computer, Openvpn ran at full speed

Thanks
