I just got OpenVPN setup last night on my two Windows XP machines,
and I'm having throughput issues when I use TCP encapsulation, but
not with UDP encapsulation. Here are the details:
TCP ontop of TCP is a bad idea. Use UDP tunnels
I have two PCs configured with OpenVPN that share the same subnet
on a single gigabit ethernet switch. The server's IP is 192.168.0.1
and the client's IP is 192.168.0.210. I tested throughput by
copying a 62.8 MB file in three different configurations.
1) With no tunnel. The file transfer took about 2 seconds, which is
roughly 32Mbps
2) With a UDP tunnel with no encryption. The file transfer took 18
seconds, which is about 3.65Mbps.
3) With a TCP tunnel with no encryption. The file transfer took 370
seconds, which is about 177Kbps.
Try checking with a network sniffer that the packet sizes are not too
big,
and then try fiddling with the packet size.
