Which Java profiler is better: JProfiler or YourKit? [closed]

Answer 1

None of the tools other than JXInsight perform real database transaction analysis:

JXInsight's Probes technology is also the only one that could even run in production considering that we out perform netbeans profiler by 20x and yourkit 100x in SPECjvm2008 benchmarks.

I am the architect of JXInsight so of course I am completely biased but at the same time I am probably more qualified than most in the Java industry to make such a claim since I have devoted the last 8 years to performance analysis for some of the most demanding of Java/J2EE application in production.

I should be point out that JXInsight is designed for software performance engineers and not just for the occasional adhoc profiling session. We have more than 4000+ system properties to configure the runtime and 600+ technology extensions libraries so it might be overkill unless one has a complex problem to solve and/or using the same tool across development, test and production is paramount.

Answer 2

Yourkit It's low overhead, stable, easy to install on the JVM to be profiled (just one dll) and powerful. For analyzing heap dumps it's the only profiler that comes close to the Eclipse Memory Analyzer.

Answer 3

I've used JProbe, OptimizeIt, and YourKit all extensively and they're all capable tools. Of the 3, my all around favorite is YourKit.

The one killer feature in JProbe is the ability to move from a perf snapshot to annotated source (with counts and timings). I found that to be exceptionally useful.
