The server is a 4-core Linode VPS

My router is a 4-core Atom box

Both are running (he upgraded mine to be the same ...)

That's what the iperf results look like to me. Really no difference at all.
Anywhere else I can tweak ?

This is on an advertised "16X3" connection. When I do speed tests online, I
get 18Mbps using the local connection (over IPv4), and ~ 15.5Mbps over the VPN
(using IPv6).
