Subject Timers, and how they affect results?
Date Wed, 09 Sep 2015 18:21:02 GMT
Hi, 

Should jmeter include timer delays in the results?
My tests has a Uniform Random Timer at the thread-level, such that:

THREAD_ONE
   UNIFORM RANDOM TIMER (max 100ms)
   HTTP SAMPLE 1
   HTTP SAMPLE 2
   HTTP SAMPLE 3
   HTTP SAMPLE 4
   HTTP SAMPLE 5
   HTTP SAMPLE 6
   HTTP SAMPLE 7
   HTTP SAMPLE 8
   HTTP SAMPLE 9 ...
 (hundreds of samplers)

Thread count is 100, rampup is 100. 


WITHOUT TIMER DELAY
====================

3.696, 1.709, 2.447 (recycle tomcat)
3.801, 1.670, 2.488 (recycle tomcat)

WITH TIMER DELAY
================
3.678, 2.945, 5.305   (recycle tomcat)
3.425, 2.974, 5.709

   (time is in seconds)

It was my understanding that timers are not included in the results.  But consistently, 
my tests with the timers are nearly double the time than those without after the first run.


What is going on here?
Why is the time for the 2nd and 3rd iteration double?
Is there a way to exclude timer delays from the results? 
Is there a flaw in my process?

Thanks
