you should also run macrobenchmarks. We maintain a macrobenchmarking tool
called https://github.com/elastic/rally[Rally]
which you can use to measure the performance impact. It comes with a set of
default benchmarks that we also
https://elasticsearch-benchmarks.elastic.co/[run every night]. To get started,
please see https://esrally.readthedocs.io/en/stable/[Rally's documentation].

### Конкурентность лучше параллелизма? { #is-concurrency-better-than-parallelism }

Нет! Мораль истории не в этом.

### Concorrência é melhor que paralelismo? { #is-concurrency-better-than-parallelism }

Não! Essa não é a moral da história.
