[December 16, 2011] Azul Systems Rolls Out Open Source Tool to Measure Variations in Java Performance Tweet Dec 16, 2011 (Close-Up Media via COMTEX) -- Azul Systems, a provider of Java runtime scalability solutions, announced the release of jHiccup, an open source tool designed to measure the pauses and stalls (or "hiccups") associated with an application's underlying Java runtime platform. According to a release, the new tool captures the aggregate effects of the Java Virtual Machine (JVM), operating system, hypervisor (if used) and hardware on application stalls and response time. jHiccup allows developers, systems operators and performance engineers to create and analyze response time profiles, and to identify whether causes of application delays reside in the application code or in the underlying runtime platform. jHiccup is completely transparent and non-intrusive to the application, has zero performance overhead in operation, and is compatible with all Java applications using any JVM. "Application performance is only as consistent as the underlying runtime platform," said Gil Tene, CTO at Azul Systems. "Java developers and IT organizations need easy-to-use tools that measure responsiveness at the JVM level and below to properly characterize the inherent runtime platform hiccups and execution stalls. This data is critical to allow developers to focus on the right parts of the runtime stack to improve the performance consistency and reduce the latency of their Java applications." jHiccup captures, logs and displays response time fluctuations in the runtime platform via "Hiccup charts." The tool does not measure delays caused by the application's code, but instead captures the stalls caused exclusively by the underlying runtime platform that would be visible to and affect any application thread running at the time of the stall. The data collected by the tool and the associated Hiccup charts allow IT organization to better isolate application performance, latency and delay problems, and to resolve them. jHiccup free download: http://www.azulsystems.com/jHiccup ((Comments on this story may be sent to [email protected])) [ Back To TMCnet.com's Homepage ]
