JMeter threads are intended to simulate independent users, so generally the focus is on ensuring that threads *don't* have to wait for each other. The Synchronizing Timer is about the only test element that allows threads to wait for each other; however it is not what you want. There's an enhancement request (with patch) for adding semaphores as test elements: http://issues.apache.org/bugzilla/attachment.cgi?id=20817 It requires Java 1.5. > Is this possible with the Interleave Controller? > > Thanks, > Andrej > > > > On Jan 20, 2008 10:03 PM, matthew sporleder <[EMAIL PROTECTED]> wrote: > > > On 1/20/08, Andrej van der Zee <[EMAIL PROTECTED]> wrote: > > > Hi, > > > > > > I am new to JMeter and I have an issue I am not able to solve.
