Bug: Post-processors run in reverse order?!
Post-processors seem to run in reverse order. For example:
Sampler
+-- User Defined Variable (sets testVar to "first")
+-- Beanshell postprocessor 1 (writes "Post 1 " + testVar)
+-- Regular Expression Extractor (changes testVar to "second")
+-- Beanshell postprocessor 2 (writes "Post 2 " + testVar)
In the log file, I expect:
Post 1 first
Post 2 second
But instead I get
Post 2 first
Post 1 second
This indicates that the three post-procs are called in reverse order.
I noticed this while debugging my test plan this morning. When I
realized what was happening, I reversed the order of my 5 postprocessors
and all was fine. I tried a few simpler test cases and the behaviour was
consistent. It only happens for post-processors; preprocessors,
assertions and configs seem to be OK.
Running Jmeter 2.2, Java 1.4, WinXP.
Is this a known problem at all?
Thanks,
Bennett.

What a coincidence... I'm just using JMeter again after an absence of 3
months, and just hit this problem. I did search the list archives, but
didn't notice the discussion because it was in a seemingly unrelated
thread. I just wanted to be sure that this behaviour is consistent so I
can rely on simply reversing my postprocessors. It seems that this is
the case.
As always, thanks very much for your help, Sebb!
Cheerio,
Bennett

Huge difference in results
Posted by Alex Turner <Al...@Project-Network.com>.
One simple possibility is that the web server is trying to resolve the names of the clients. The slow response machine's name cannot be resolved so the web server is waiting until the name resolution fails before it serves up the page. I would try looking in the web server logs and see if you can spot any difference in entries for requests originating from the odd machines to requests originating from the rest of the machines.
Just a thought :-)

Hi,
We are using few machines to execute our load testing.
Problem is one guy getting some abnormal values for test cases.
If we run the same test case in another machine, values are normal.
(when I getting avg time:1000ms he is getting 10000ms for the same test case
in same time frame). Can u pls explain the reasons for this behaviour?
Thx & Rgds,
Manjula

First check I would probably do is to ensure that the time in all the
machines are in synch or not. (Hope you using multiple load canons).
Use ntp or so to ensure that all the box timings are in synch. Can you
rerun ur benchmark and post it here?
