during -- node07, 60s window, 60 samples, wrapping benchmark.sh

  VERDICT   Something else was running inside the benchmark window, so the
            result measures both.  Fix that before reading the bottleneck
            below.

  WARN      something else ran     backup took 71% CPU in 18% of the samples
  INFO      what limited the run   io for 68% of the run (waiting on storage)
  INFO      warmup in the average  steady only from 9s, so 15% of the samples are warmup
  ok        cpu clock fell, hypervisor took time, storage throttled (+3)
