Riak SmartMachine Benchmark: The Technical Details

Remember the Riak in the Joyent cloud benchmark? There’s a post providing many more details about the tests run:

The goal of the study was to demonstrate a baseline for users to understand Riak’s performance, stability, predictability, and linear scalability.  The systems were not tuned for optimal performance.  Instead, we chose to take standard 4 GB Riak Smartmachines and demonstrate throughput and latency for various access patterns and object sizes.

The conclusions is what made me say it got atypical (in a good sense) results:

Our benchmark tests bring us to the following conclusions:

  • Riak behaves predictably under high loads – depending on system resources, Riak exhibits either predictable, steady-state throughput with low errors or degrades gracefully with low errors.
  • Riak demonstrates stability under high loads – very few errors, no node failures under load, and behavior in line with expectations.
  • Riak demonstrates linear scalability – adding or removing capacity adds or subtracts a predictable amount of capacity from the cluster.
