IPSec VPNs use UDP and IPSec protocols (you can just think of both as 
"udp")  rather than TCP for transport so I would think they have less 
"overhead" as you call it.  TCP based tunnels (like SSH tunnels) do all 
sorts of things that will totally screw up latency (congestion control, 
retransmit lost packets, etc).  For most applications this is not an 
issue.  Who cares if there's 2000ms of jitter on an HTTP request?
