Java -agentlib:hprof=heap=sites -cp target/ .profilerproject.PrimeCalculator This identifies the most heavily allocated object types, and the TRACE at which those allocations occurred. Heap Allocation profiles (heap=sites) which provides a sorted list of allocation sites. Some of the types of profiling you can do with hprof are: In order to get the list of options available for hprof use: The options to hprof are provided as a commas separated list. The data generated can be in textual or binary format, and can be used to track down and isolate performance problems involving memory usage and inefficient code. By supplying HPROF options at startup, users can request various types of heap and/or cpu profiling features from HPROF. hprof is actually a JVM native agent library which is dynamically loaded through a command line option, at JVM startup, and becomes part of the JVM process. There are command line as well as GUI tools to perform different profiling tasks for Java applications. (it's possible to view the response as HTML etc., but the timings are not included in any samples, and only one sample in one thread is ever displayed at a time).There are several tools to profile Java applications. Nor does it render the HTML pages as a browser does In particular, JMeter does not execute the Javascript found in HTML pages. However JMeter does not perform all the actions supported by browsers. JMeter is not a browser, it works at protocol level.Īs far as web-services and remote services are concerned, JMeter looks like a browser (or rather, multiple browsers)
