There are times when memory profiling will provide a clearer picture than execution profiling to find execution hot spots. In this article Kirk Pepperdine talks through some indicators for determining when to use which kind of profiler.
We mostly ship software by date, squeezing all development and testing efforts toward that deadline. We prioritize what we think is important, and once our application passes a certain quality level, we’re ready to go live. But even when we do ship, can we tell the readiness status of our application?
In July Monica Beckwith explored the theory of the new G1 GC Garbage First Garbage Collector. In this second installment, Monica delves into more practical aspects and provides guidance for tuning.
A question that often comes up on Performance Management – Agile talks about team performance so why am I measured on individual goals which have little to do with team performance? 4
Many articles describe how a poorly tuned garbage collector can bring an application's SLA to its knees. The G1 collector replaces the conventional algorithms with a concept of “regions” 4
In the world of application delivery, performance tuning still eludes the mainstream. InfoQ spoke to 5 luminaries of the performance monitoring space about it. The result was quite an active debate. 1
Michael Slinn examines how to benchmark JVM concurrency options for JVM-based langauges including Java and Scala. 2
The book "Solving Enterprise Applications Performance Puzzles" by Leonid Grinshpan explains how to boost the performance of enterprise applications. 3
Java Performance, by Charlie Hunt and Binu John, provides performance tuning advice for both Java SE and EE applications. InfoQ reviews the book, and talks to the authors about their approach.
Joachim walks you step by step through using open source tools like JMap, VisualVM, BTrace, and EurekaJ to effectively diagnose performance and memory problems in your Java apps. 9
