good old friend JMeter

JMeter is one of those primitive animals that never goes extinct.

Decent presentation:




Excellent comparison with SoapUI

JMeter is good for a VERY quick and dirty PERFORMANCE test of a service.

This is an excellent book - not only about technology but mostly about culture, leadership, teamwork, innovation.

I don't share the enthusiastic vision of the author for which life is about serving corporations to beat competition and cut jobs. However it's an educational book.
