We evaluate the maximum number of bytes, or throughput, achievable by the instance, still with FIO but configured with the following parameters.

To measure IOPS, we use the well known tool Flexible I/O Tester (FIO) the following configuration:

  • 1MB blocks
  • Sequential access
  • Read then Write
  • Direct access to device without filesystems
  • libaio engine
