Recent times, Uber has been experiencing exponential growth in its traffic. Recent spike in traffic volume exposed several memory related performance bottlenecks in their platform: long garbage collection (GC) pauses, memory corruption, out-of-memory (OOM) exceptions, and memory leaks. In this brilliant article, the Uber engineering team summarizes their optimization journey: What all the challenges they faced, the tools they used, best practices they followed to fix their application’s performance bottlenecks.Continue reading “Uber optimizes Garbage collection performance using GCeasy”
JVM has provided helpful arguments to deal with OutOfMemoryError. In this article, we would like to highlight those JVM arguments. It might come handy for you when you are troubleshooting OutOfMemoryError. Those JVM arguments are:Continue reading “OUTOFMEMORYERROR RELATED JVM ARGUMENTS”
In several journals, articles, blogs and all throughout the internet there is one common theme echoed: “Serial GC is not meant for any serious applications. It should be used only for prototype application. It’s only meant for desktop application or applications that have few hundred MBs of heap size. It shouldn’t be used in production.” To question this status quo theme, we conducted the below study on a major travel web services application in North America (Kindly apologizes, I can’t disclose their name).Continue reading “QUESTIONING STATUS QUO – ‘SERIAL GC NOT FOR SERIOUS APPLICATIONS’”
On a major B2B application different GC algorithms behaviors were studied. This application is basically a web service provider servicing SOAP and REST requests from its clients.
