In OpenVPN manual, it say you should run it as -user nobody and -root nobody in config 'to enhance security'.
So how unsafe it is to run the client as current user (or even set it to run as root)?

I have this problem that when I set user and group to nobody in config, my torrent download speed will get crippled.
It downloads normally at launch, but will crawl to 0.1kbps minutes later.

This problem does not happen when I run OpenVPN client as current user or root.

So it is actually a big security issue to let my OpenVPN run as current user instead of nobody?
