How can I measure the search run time until the first result is returned?

[zuckermanori]

I'm benchmarking performance of search queries.

I noticed that although the entire search pipeline takes long to complete, initial results are returned quickly.

how can I measure the query run time until the first result is returned?

currently i'm measuring the entire query run time with 

history.total_run_time

but that gives me the total time and I want the time for first result.
