Usually a PC can handle quite a big number of threads without problems but think about some other effects that might result in wrong measurements of server response times:
A good idea is to monitor the workload of your CPU. If it is around 100% it might be to much meaning your CPU is overloaded and the measured response times might be incorrect. On the other hand network effects might occur if you run on to much load on a single PC or a single network. If you produce more network traffic than it can handle, your measured times will also be incorrect because of network effect. Just calculate: If you run 1000 threads and the traffic per thread is just 1 Kbytes per request you have to transfer about 1 Mbytes which might be to much for your internet/intranet connection. In former projects we figured out that running jmeter on several PC in best case on several networks is best practice to measure the "right" response times Olav -----Ursprüngliche Nachricht----- Von: Joseph Barefoot [mailto:[EMAIL PROTECTED]] Gesendet: Dienstag, 9.
