Vaadin7 Performance Problem and JMeter Test

Hi everybody,

i want button click test(multithread) with apache jmeter. but i got unexpected clientID number error.i disabled syncID but i can not disable clientID.

how can i perform this test?i want to perform a performance test to simple vaadin 7 button click example.because i heard made with vaadin7 login page broken down when about 300 users visited to this page.however it was a not problem when you wrote it the same page with php?

Have you checked DiagnosticServlet add-on? There is couple of good links there too how to setup scalability testing with Jmeter
