05fdb97df46d0a0675b93e9791bd5d498e5e5117 [doc] Update and extend benchmarking.md (Antoine Riard)

Pull request description:

  Trying to make benchmarking docs a bit more friendly.

  If you have any more ideas, specially on the Notes section, which component need more benchmarks.

  (oh isn't a write-up somewhere to generate flame graphs for core ?)

Running Running

For benchmarks purposes you only need to compile `dash_bench`. Beware of configuring without `--enable-debug` as this would impact
benchmarking by unlatching log printers and lock analysis.
