A bare bones yesod app for performance testing. Stolen almost verbatim from https://github.com/yesodweb/benchmarks/blob/master/pong/yesod.hs.

Test by building and running yesod-test:

cabal-dev install && cabal-dev/bin/yesod-test

and calling httperf:

httperf --hog --num-conns 1000 --num-calls 1000 --port 3000 --server localhost
