I wanted to run another round of performance benchmarks for `gnat` to see how it's request throughput has changed with the introduction of the `ConsumerSupervisor` which handles things like processing each request in its own supervised process.

I used a CPU-optimized digital ocean droplet with 16 cores, gnatsd 1.3.0, erlang 21.1 and elixir 1.7.3.
You can read the setup instructions below for more details and the `results_by_concurrency.md` contains details about a lot of different runs.

I'm trying to measure the overhead in the system, so the requests are 4-byte "PING" messages and the responses just echo back the same 4 bytes.
The `gnatsd` broker is running on the same host to

# TL/DR; You can do 70k+ synchronous requests/sec

> 4 server connections
> 8 cliennt connections
> 2048 concurrent requests

```
It took 57.140892sec to make 4096000 requests
	71682.46515997685req/sec throughput
	min: 156µs
	max: 146315µs
	median: 24371µs
	90th percentile: 47424µs
	average: 27520µs
