I have two VPS's - One is running 2008 Server R2 and the other is a Ubuntu 12.04 installation. I am using the Windows VPS for RD sessions for Quickbooks and a couple other apps and using the Ubuntu VPS as a NFS file store as well as a OpenVPN endpoint. The problem is that NFS performance through the VPN is downright horrible and by this I mean often times it wont even connect and times out frequently.
If I set up the NFS outside the tunnel performance is okay...not great but manageable so I know its the VPN tunnel.
Are there any tweaks for openvpn or NFS I can play around with to boost performance?
