There is no question about that. MediaProxy avoids over 90% of the work 
that a user space solution does (polling over the sockets and copying the 
data from kernel space and user space and back). I would expect it to be 
at least an order of magnitude faster, but I have no benchmark data to 
know how faster it actually is. What I do know, is that a solution using 
the linux kernel networking QoS implementation to throttle network 
connections, which uses a very similar but more expensive workflow, it's 
able to drive 600Mbps in + 600Mbps out, handling millions of connections 
(in the case of a media relay, the number of connections is much smaller, 
so the strain on the CPU is reduced).
