Hi,
we are using OpenVPN on Debian Wheezy and from time to time we have a high latency over our OpenVPN tunnel:
We are using the following version:
2.2.1-8+deb7u3
A checked the system resources and they are looking fine. A ping to the public ip of our OpenVPN-Server is stable and we can't see the higher latency.
