Application scalability and Java HPC
Java High Performance Computing (HPC ) refers to the ability of an application to handle different levels of usage. A highly scalable application will only require additional resources in order to handle higher usage loads. An application that is not scalable will require modifications to the application itself in order to handle higher usage loads. Java HPC allows a program to handle different loads, but may limit application performance and functionality. In this section on Java HPC, get the latest news, research and tutorials to help make your applications fit your business needs.
Avoid JVM de-optimization: Get your Java apps runnings fast right fromt the start
13 May 2014
Tip - Many organizations warm up their JVMs before heavy loads and transaction volumes occur, but well intentioned routines that are poorly planned can actually de-optimize the Java runtime. Here are some tips from some of the industry's foremost experts on...
Optimizing JVM performance with smart garbage collection (GC) and bytecode caching
02 May 2014
Tip - Some JVM optimization techniques can actually slow down the Java Virtual Machine, but by optimizing garbage collection and using overriding the bytecode caching mechanisms, DevOps professionals can increase the performance of their systems.
Improving Java performance by minimizing Virtual Machine (JVM) latency
01 May 2014
Tip - Users demand that their applications run fast, but working with Java bytecode presents optimization problems that other architectures do not encounter. Here we look at how to improve the performance of the Java Virtual Machine (JVM) by minimizing the...
Tomcat performance optimization through consolidated log file handlers
05 May 2013
Tip - By default Tomcat uses several log file handlers, but performance can easily be optimized by configuring the server to use only one.
Consistent application performance: It's not always about speed
24 Oct 2012
Tip - When developing applications, the response time is always an important metric. But inconsistent response times can often be more aggravating than slow sites. Make sure you take response time consistency into your application performance reviews.
