I'm trying OpenVPN to create a secure link between my home server and wherever I decide to travel. Sadly some of my media at home can't play very well over the network, so I'm trying to find out where the bottleneck is. So I got a PC and my RPI doing some bandwith tests. Both of them are connected to the same switch using the same media (CAT 5e cables).
If I do the test from the PC to the server through the OpenVPN link I get 7.6MB/s which is more than decent considering I don't have any media that goes beyond 1MB/s bit rate. However, if I do the test from the RPI to the server through the OpenVPN link I only get 500KB/s. I don't understand why such a difference in speed if we are using the same media basically. I can get 7MB+ speed between the PC and the RPI.
The only thing that I can think of is that maybe the CPU is the bottleneck? If that's the case maybe I can just route the traffic through the PC, if so how would I go about it?
Tests were done using nc
, so maybe not the most accurate but there's still a big difference in bandwidth speeds.
