conclusions

  • no diff between ebs encrypted and not
  • instance store faster by: 10 for writes, 5 for buffered reads (same as ebs for cached)
  • bonnie++ tests would take with grain of salt because of small volume:mem size (bonnie++ warns that mem should be half of test file size to be usable) ... they show EBS having 2 x faster read (output), and comparable write (input)
