Performance issues with raspberry pi 2

[Andreas Andersson]

Just built an image for the raspberry pi without the witness options.. Will
try to build with TARGET_ARCH=armv6hf later on. Eager to test the
performance of tornadoweb on the rpi first. :)

Will come back with benchmarks later. What else would be nice to benchmark?
Is there a standard set of benchmarks that I can run and provide results
for?
