    Include Query Timings

    • When making a query,
      you can request to get detailed stats of the time spent by RavenDB on each part of the query.
      E.g. duration of search, loading documents, transforming results, total duration, etc.

    • By default, the timings stats are Not included in the query results, to avoid the measuring overhead.

    • To include the query timings in the query results:
      add a call to the timings() method in your query code, or add include timings() to an RQL query.
      See examples below.

    • In this page:

    Include timings in a query 

    $timings = new QueryTimings();

/** @var array<Product> $resultsWithTimings */
$resultsWithTimings = $session->advanced()->documentQuery(Product::class)
    ->timings($timings)
    ->search("Name", "Syrup")
    ->toList();

/** @var array<QueryTimings> $timingsMap */
$timingsMap = $timings->getTimings();
    from "Products"
where search(Name, "Syrup") or search(Name, "Lager")
include timings()

    View timings

    • The detailed timings can be viewed from Studio's Query view.

    • Running an RQL query with include timings() will show an additional Timings Tab
      with a graphical representation of the time spent in each query part.
