Interesting thing about system.out.println how huge bottleneck it creates being used while asking db through RESTful webservice. This article pushed me to experiment by my own with VisualVM and JMeter. Both are great tools.
(About VisualVM, yesterday I’ve made a complaint about it, but today I’ve got notification to upgrade Visual sampler what really helped and turned this tool into very handy stuff;)
