Is it possible to increase client speeds to OpenVPN servers if the client is using multiple tunnels? Most servers only allow for a maximum of 100-120 megabit throughput; this severely limits users throughput.. Can multiple tunnels overcome this obstacle? If so, what are the directives necessary to about implementing this? If not, what are other options users can make to ensure they can double their 100-120 megabit throughput:?:

you can definitely create as many tunnels as you want, but you'll end up with multiple uplink interfaces on your client and then you have to deal with that in some way. That will not be something to fix at the "OpenVPN layer" but it's something to solve on your client system. This would be a common case of multi-homing.
If the client system is linux, you could implement a routing table that tries to do load balance among the available uplinks. Still, it is not so easy to get "as much as possible"

I've seen this 100mb speed limit mentioned a few times, but not really explained. Can someone point me to a source where I can read more about where the bottleneck is and why it exists?
