How to send requests (instead of sending for duration seconds)

Question

Current wrk configuration allows sending continuous requests for seconds (duration parameter).

Is there a way to use wrk to send requests and then exit.

My use case: I want to create large number of threads + connections (e.g. 1000 threads with 100 connections per thread) and send instantaneous bursts towards the server.

Did you find a solution? – David Brossard Nov 04 '19 at 21:41 — David Brossard, Nov 04 '19 at 21:41

You can do it with LUA script:

local counter = 1

function response()
   if counter == 100 then
      wrk.thread:stop()
   end
   counter = counter + 1
end

Pass this script with -s command line parameter.

Where would you write this script? – David Brossard Nov 04 '19 at 21:40

Put the code to any file and pass it to the `wrk` after -s parameter. – Artem Klevtsov Nov 16 '19 at 07:13
This does not stop wrk itself. It keeps on running until it reaches the duration you specified with `-d` – djuarezg Sep 15 '22 at 14:52

I make changes to wrk to introduce new knobs. Let me know if anyone is interested in the patch and I could post it.

I added a -r to send exactly requests and bail out.

Hi, I'm interested in this. Could you post this patch, if you still have the code? – wotocem Jun 15 '21 at 16:53
