San Francisco’s QCon was expecting a smaller crowd, but ended up bursting at the seams: the event sold out weeks ahead of time and in many sessions it was standing room only. Targeted at architects and operations folks as much as developers, QCon was heavy on the hot topics of the day: SOA, agile, and […]
Here’s a guest blog from one of AppDynamics’ international partners, Stefan Zoltai from sysPerform. Stefan wanted to write about how he used AppDynamics to solve a performance problem for a major telecom company in Switzerland—and we said, sure! Take it away, Stefan… I’d like to talk about how we used AppDynamics for a major production […]
Memory, Memory, Memory… Memory is a critical part of Java, in particular, the management of memory. As a developer, memory management is not something you want to be doing on a regular basis, nor is it something you want to do manually. One of the great benefits of Java is its ability to take […]
It’s time for another update to our series on Top Application Performance Challenges. Last time I looked at Java’s synchronization mechanism as a source for performance problems. This time around I take on what is likely the Performance Engineer’s bread and butter … slow database access! Behind this small statement lies a tricky and multifaceted […]
This summer, I had a chance to sit on a panel at DevOps Days with a few industry colleagues to discuss the role of monitoring, testing, and performance in solving DevOps issues. It was a lively discussion on the teams, tools, and techniques that play a role in managing application and network performance.
This post is part of our series on the Top Application Performance Challenges. Over the past couple of weeks we helped a few DevOps groups troubleshoot performance problems in their production Java-based applications. While the applications themselves bore little resemblance to one another, they all shared one common problem. They were full of runtime exceptions. […]
This is the first post in a series on the Top Application Performance Challenges. Of the many issues affecting the performance of Java/.NET applications, synchronization ranks near the top. Issues arising from synchronization are often hard to recognize and their impact on performance can be become significant. What’s more, they are often, at least in […]
