Hi all,
Even if with small users (e.g. total 1000) in distributed mode, I have a sudden increase in response times through the end of the test distorting the result. For ones with high response times, Jmeter throws "Non HTTP response code: java.net.ConnectException/Non HTTP response message: Connection timed out: connect" error. All my machines (18 slaves 1 master) are Windows.
At what point I make mistake? Could you please help me?
How many users you have in Thread Group(s)?
In order to get 1000 users with 18 slave machines you should have 55 threads (virtual users) in all Thread Groups.
If you have 1000 users defined in the Test Plan and have 18 slave machines - you're kicking off 18000 threads which might be too much for your application.
You can check how many exactly virtual users were active at the given moment of your test execution using Active Threads Over Timer listener (the listener can be installed using JMeter Plugins Manager)
