Hi,
I am not able to run test plan for 270 concurrent users. Please find below
all my details.
Test setup Details-
1> Jmeter Client
HEAP=-Xms512m -Xmx1024m
2> Jmeter Server(quantity:1)
HEAP=-Xms512m -Xmx4096m
3> Tomcat Server
JAVA_OPTS=-Xms1024m -Xmx1024m
4> For 260 Concurrent users, changed the default maxthreads limit
from 200 to 2500. Below 2500 maxthreads limit,
Jmeter throws a “java.net.ConnectException: Connection refused:”
5> Test Plan:-
- User will hit home page of a web application
- User will go to products page
- Products page has 9 product images.And each src of images is basically
URL.
So 9 http sample requests for 9 product images
- User will go to product detail page
Total Sample Requests => 12 * 260 = 3120
6> Finally, it works properly without any error.
Problem:
--------
For 270 concurrent users ( with the same configuration mentioned above),I am
getting error message for
few http sample requests.
Error message: “java.net.ConnectException: Connection refused:”
What should I do to resolve the problem.
Questions:
----------
1> To resolve the problem, should I use another Jmeter server? Currently, I
am using one Jmeter server
2> Should I gradually increase the maxthreads limit in tomcat's "server.xml"
to check at what point it works
properly for 270 users?
3> My target is 2500 concurrent users.
So to test this how many Jmeter servers I need.
Also what should be the Heap size in those servers.
4> Is it require to increase the tomcat's JAVA_OPTS ? Currently, I had given
1 GB.
Thanks
Maumita
