Entrez Invert Performance Measurement

  InvertTrials() {
    echo -e "<Trials>"
    for tries in {1..5}
    do
      cat "$1" | rchive -debug -proc "$2" -invert
    done
    echo -e "</Trials>"
  }

  for proc in {1..8}
  do
    InvertTrials "carotene.e2x" "$proc" |
    xtract -pattern Trials -lbl "$proc" -avg Rate -dev Rate
  done

Execution Profiling

  cat carotene.e2x | ./rchive -profile -invert > /dev/null
  go tool pprof --pdf ./cpu.pprof > ./callgraph.pdf
