Hi Heiko,

This command contains worker counts already. No need to start workers
manually by using ssbench-worker.

ssbench-master run-scenario -f large.scenario -u 200 -o 4000 --workers 4


   - Ensure there’s no any workers “$ps aux | grep ssbench”
   - Try to kill workers “$ssbench-master kill-workers”
   - Try to start with lower “user count” (-u) and less operation
   counts(-o).

ssbench-master run-scenario -f large.scenario -u 10 -r 30 —workers 1

    "name": "tiny",
    "size_min": 100000,
    "size_max": 160000

    "size_min": 400000,
    "size_max": 4000000
  }],

}
