You need to analyse what these errors are. > Throughput 18.89711235 > KB/sec 249.9800706 > Avg.

Perhaps the test ended abruptly? Did you set the test to continue on error? Are there any conditional controllers in the test plan?

Impossible to say without knowing what the performance requirements of the server are, and what the test plan is trying to emulate. However, the fact that there are some errors when increasing the number of threads to 25 could indicate a problem with the server. Or it could just be an error in the test plan - e.g. it is not correctly set up for multiple threads. Try running 2, 3 and 4 threads. If these all work, then the test plan at least seems to be suitable. Also, the large increase in the maximum sample time from 5secs to 69secs needs to be investigated. > finally what you can see from this results? is it good? bad? The figures say nothing much in isolation. What load is the application under test supposed to support? Are there max. response times?
