[Bug 64835] New: Question about response time difference in gui mode and non gui mode

https://bz.apache.org/bugzilla/show_bug.cgi?id=64835

            Bug ID: 64835
           Summary: Question about response time difference in gui mode
                    and non gui mode
           Product: JMeter
           Version: 5.1.1
          Hardware: PC
            Status: NEW
          Severity: major
          Priority: P2
         Component: HTTP
          Assignee: issues@jmeter.apache.org
          Reporter: dmlwnd100@naver.com
  Target Milestone: JMETER_5.3.1

Hello, I'm using in JMeter for performance testing.
JMeter is so nice performance tool! Thanks for this good service!

But I had a question a few days ago.
I did a response time test for 1 Request in Non-Gui mode and Gui mode.

However, There was a difference in response time. In the case of Non-Gui mode,
it took more than 2 seconds, and In the case of Gui mode, it took 100ms.
(When analyzing through the report dashboard, the connect time and latency also
exceeded 2 seconds)

In the case of a large number of concurrent users, there may be a difference
because the number of active threads is different, But the above case is really
not understandable.

Can I get some help or comment?
Thanks JMeter's Guys!

I don't think this should be asked here but more on user mailing list.

Few notes why the results are not usable:

- You're using a 3rd party website where we have no guarantee of response times
as network can vary a lot
- The results with 1 requests cannot be considered as there are too few samples
- The results with 10 requests are the same and in the GUI_Requests_10user.csv
, there are results with 1 to 2 seconds similar to non gui

Please run such results against some local website like httpbin
(https://httpbin.org/):

docker run -p 80:80 kennethreitz/httpbin


If such differences persist please reopen.

Thanks for your quickly response!

Yesterday I didn't give you enough data to confirm.
I am sorry for not giving detailed information!

First, I'll answer the question.

1) I used to Thread Group - HTTP Request Sampler - View Results Tree Set!
   (Please refer to the attached file, For reference, JMeter Version is 5.3)
2) OS : Windows 10, Java : 1.8, JMeter : 5.3
3) I'm not used third party library in this case.

I'll attach the test jmx file that I recreated myself and the result of the csv
file that I experimented in GUI mode and Non GUI mode together.
( GUI_Requests_1user.csv, NonGUI_Requests.1user.csv, GUI_Requests_10user.csv,
NonGUI_Requests.10user.csv )

The part to check intensively is response time information.
Even though one user was tested, it exceeded 2 seconds in the case of Non-GUI
Mode.

Thanks for your favor!

Thanks for the nice words, but to investigate your performance problems, we
need a simple test plan to reproduce it or at least more information on what
you are trying to do.

* Can you post a simple test plan, that shows this behaviour? (Which sampler do
you use? Any controllers, functions, ...?

* What is your OS, Java and JMeter version?

* Are you using third party plugins (if so, which)?

Always remember, we can't see, what you are doing, so you have to describe your
steps in detail.
