    Reg vdbench iorate is getting decreased for every run




      I am running the below parameter file to test a zfs volume(4TB).





      My understanding is that

      It performs 4K, 100% write, 100% random for 60 sec with max iorate possible. Please confirm.

      When I repeat the same test, the IOPS values are going down. What could be the reason?


      Also what is the kind of write IO Pattern it uses -Is it full random IO, pseudo random IO or Repeating bytes?.How to configure these values. Please let me know.
