     1  # Consul Benchmark Results
     2  
     3  As part of a benchmark, we started a 4 node DigitalOcean cluster to benchmark.
     4  There are 3 servers, meaning writes must commit to at least 2 servers.
     5  The 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  
    12  We 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  
    20  Below is the output for a test run on a benchmark cluster. We ran the benchmark
    21  several times to warm up the nodes, and this is just a single representative sample.
    22  
    23  Note, that a single worker was running the benchmark. This means the "stale" test is
    24  not representative of total throughput, as the client was only routing to a single server.
