1# Consul Benchmark Results
2
3As part of a benchmark, we started a 4 node DigitalOcean cluster to benchmark.
4There are 3 servers, meaning writes must commit to at least 2 servers.
5The cluster uses the 16GB DigitalOcean droplet which has the following specs:
6
7 * 8 CPU Cores, 2Ghz
8 * 16GB RAM
9 * 160GB SSD disk
10 * 1Gbps NIC
11
12We used `bonnie++` to benchmark the disk, and the key metrics are:
13
14 * 188MB/s sequential write
15 * 86MB/s sequential read-write-flush
16 * 2636 random seeks per second
17
18# Output
19
20Below is the output for a test run on a benchmark cluster. We ran the benchmark
21several times to warm up the nodes, and this is just a single representative sample.
22
23Note, that a single worker was running the benchmark. This means the "stale" test is
24not representative of total throughput, as the client was only routing to a single server.
