Comparative Benchmark Numbers @ Rackspace

I've taken the benchmarks from Matthew Rothenberg's phoenix-showdown, updated Phoenix to 0.13.1 and ran the tests on the most powerful machines available at Rackspace.

Results

Framework	Throughput (req/s)	Latency (ms)	Consistency (σ ms)

When you want to generate the flame graph, run the following (folder locations taken from install script):

sudo sysctl kernel.kptr_restrict=0

# This is an example of metaprogramming in the Elixir language.
# 
# We will define a domain specific language (DSL) for the definition
# of a service which is watched by several sensors.
# Each sensor watches some property/functionality of the service and
# returns the result of the check.
# 
# To determine if the service is functioning properly, we need functions
# to run all the sensors' code and gather the returned data.
