Consul Benchmark
================
This repo contains the Packer automation necessary for the Consul benchmarks.
This repo contains the automation necessary for the Consul benchmarks.
There is a single main Packer file `bench.json`. To use it, the variables
for `do_client_id` and `do_api_key` must be provided. There correspond to
your DigitalOcean client id and API key.
for `do_client_id` and `do_api_key` must be provided. These correspond to
your DigitalOcean client ID and API key.
When Packer runs, it will generate 3 images:
* bench-bootstrap - Consul server in bootstrap mode
* bench-server - Consul server
* bench-worker - Worker node

# Consul Benchmark Results
As part of a benchmark, we started a 4 node DigitalOcean cluster to benchmark.
There are 3 servers, meaning writes must commit to at least 2 servers.
The cluster uses the 16GB DigitalOcean droplet which has the following specs:
* 8 CPU Cores, 2Ghz
* 16GB RAM
* 160GB SSD disk
* 1Gbps NIC
# Output
Below is the output for a test run on a benchmark cluster. We ran the benchmark
several times to warm up the nodes, and this is just a single representative sample.
Note, that a single worker was running the benchmark. This means the "stale" test
is not representative of total throughput, as the client was only routing to a
single server.
We also did an initial run where we got lots of noise in the results, so we
increased the number of requests to try to get a better sample.

# Profile
In order to probe performance a bit, we ran the get-stale benchmark on the
leader itself and collected pprof data. Here's the output of the benchmark:
