Benchmarks

Currently, I'm benchmarking the following situations:

1. n messages to single node in a cluster of m nodes.
2. Split n messages evenly between m nodes.
3. Test 1 but with async client handling.

#	n	m	sample size	seq. client	ops/s
1	1000	2	20	yes	90.2 ± 0.16
2	1000	2	20	yes	181 ± 3.05
3	1000	2	20	no	1850 ± 245

Split test does in fact achieve twice the throughput.

Performace doesn't degrade over time. Here are the results after 20 sequential test 1s:

Test 2 doesn't work with async client handling and regardless the throughput is low.

This means the project will migrate to tokio.
