Web Application Test and monitoring execution time -- running imon In terms of system performance tuning, we have previously introduced the use of jmeter-plugins and VisualVM to monitor the overall performance of the system. Sometimes, to identify the bottleneck, you need to understand the time consumed by some specific method calls. VisualVm can do this, but if profiler is used, it will consume too much re
