I'm just wondering how important these considerations are in practice.
somebody says OpenVPN is "relatively slow", is that "slow" in an
academic, computer-science inefficient inter-process communication sort
of way, or slow in a my-users-will-complain sort of way? (And what
"fast" VPN method are we comparing this to, anyway? IPSec?)
It's really a matter of joining the dots...
Client -> VPN-software -> Oz -> Internet -> Canada -> VPN-software -> Server
now - where do you think the bottleneck is :-)
userland vs kernelland VPN/crypto performance issues are going to PALE
INTO INSIGNIFICANCE compared with the 200-400ms latency you will have on
that long-haul between Canada and Australia.
I should know. Our IPSec VPN WAN has links from NZ to places in Canada
and Sweden. Wanna see latency? Wanna see not being able to get more than
240Kb/s single-connection transfers on 4000Kbs links? :-)
