The Profile API provides detailed information about how each component of your queries and aggregations impacts the time it takes to process the request.

The Search Profiler in Kibana makes it easy to navigate and analyze the profile results and give you insight into how to tune your queries to improve performance and reduce load.

Because the Profile API itself adds significant overhead to the query, this information is best used to understand the relative cost of the various query components. It does not provide a reliable measure of actual processing time.
