Nice.

The intel guys already did an experimental (and fairly ugly) patch to make
the kernel try to semi-pad the destination by selecting specific sizes for
the packets sent out over TCP. They claimed a 3% speedup in specweb (or
something) from that. The argument from Dave and Alan was that it should
be done from within the web-server.
