Hey Lee,

That's surprising to hear. Indeed userspace is slower than kernel
space, but on sufficiently fast hardware you won't notice much of a
difference at those low speeds. Have you checked MTU issues? For
example, perhaps the router is trying to forward packets with 1500
bytes down a 1420 byte pipe?

Regards,
Jason
