I don't trust my ISP to give me latency-decent packet service. I've
been using a tool called Smokeping to ping a small set of machines (my
ISP's gateway, google.ca, and csclub.uwaterloo.ca (where my screen
session lives)). This gives me a history of reasonable ping times that
I can use to benchmark current behaviour of my internet connection.

Thusly, I suggest pinging the machine you are OpenVPN'ing to. Then you
can reasonably determine:
 - opening the VPN connection degrades the general latency times to that machine
 - opening the VPN connection degrates your internet connection in general
 - nothing (e.g. maybe only the OpenVPN connection gets throttled. In
this case you may want to try and alternative Smokeping "target" (I
think that's the word), such as ssh to see if it's only encrypted
traffic that gets throttled.)

Hope that helps!
