+# 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.
