Subject RE: Limit concurrent number of threads using Constant Throughput Timer?
Date Wed, 21 Jan 2009 16:06:46 GMT

Hi Adrian,

I've configured the number of threads to 3000 such that all test cases from
the .CSV file will be executed. When setting the number of threads to 50,
only the first 50 test cases will be executed..

Regards, Pieter
