# 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
|
||
|
|
||
|
We used `bonnie++` to benchmark the disk, and the key metrics are:
|
||
|
|
||
|
* 188MB/s sequential write
|
||
|
* 86MB/s sequential read-write-flush
|
||
|
* 2636 random seeks per second
|
||
|
|
||
|
# 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.
