hi a. In most cases you wont be able to run 2500 users from a single machine , so you should run multiple instances of jmeter or run it as distributed b. ConnectException is just that, the server refused your connection. There may be multiple reasons why this can be caused and all of them are application server/os specific. Your server probably cant handle the number of threads you have concurrently. You need to check your server
Unrelated Suggestions upgrade to 2.3.4 You probably shouldnt have view results tree , you might run out of memory..For large tests you should probably run in command line with all listeners disabled regards deepak On Wed, Sep 9, 2009 at 8:40 PM, Mytho Logic <[email protected]>wrote: > Hi, > > I am new in Jmeter and facing problem while load testing my web > application. > > > > I am using jmeter version 2.3.2 for my project. > > I have created a test plan of using 4 thread groups and 280 concurrent > threads. > > > > ----- > > -Test plan > > - synchronize Timer (set 280 threads) > > - Thread Group (users = 90, ramp-up periord = 0) > > a. this thread group hs 12 sample requests > > - Thread Group (users = 90, ramp-up periord = 0) > > a. this thread group hs 12 sample requests > > - Thread Group (users = 50, ramp-up periord = 0) > > a. this thread group hs 12 sample requests > > - Thread Group (users = 50, ramp-up periord = 0) > > a. this thread group hs 12 sample requests > > - View Results tree > > - View Results in table > > - Aggregate reports > > > > ----- > > 12 sample requests are -> > > 1.
