General considerations

  • To improve the validity of results, you need to perform 3-5 iterations of the same test.
  • For file tests, each test should take at least 60 seconds. The recommended time, however, is 120-300 seconds, which can negate the benefits of fast cache on some SSD drives.
  • For S3 tests, the recommended run time is at least 900 seconds, which provides more stable results.
  • When using erasure coding, throughput is usually limited at 500-800 MB/s per node, for both reading and writing (depending on specific hardware and workload). If you reach this limit, you may improve your results by spreading the load across a larger number of nodes or by adding more nodes.
