Java Microbenchmarking Harness: Go Ahead and Be a Little Bit Evil AND Java...

Wednesday, July 27, 2016
6:30 - 8:30 PM

Presented by

Will Price

We've been told that premature optimization is the root of all evil, but when you have performance-critical code and you suspect it's slow or that another approach will be an improvement — how do you know? Do you eyeball it? Do you throw the code in a loop surrounded by system time calls? How do your assumptions hold up against the JVM's optimizing JIT compiler?

We'll look at how to get up and running quickly with JMH, the Java Micro-benchmarking Harness, written by the developers that maintain OpenJDK. It's a tool designed to provide statistically accurate performance measurements, while helping you avoid the numerous JVM-related pitfalls that often skew the results in more naive approaches.

William Price is a software architect at PROS, Inc., a global leader in price optimization software and based in Houston, Texas. His experience includes designing and implementing complex and high-performance computation engines that power PROS' science-driven enterprise solutions.

Our sponsor will also give a brief talk about their new product, Java Security Analyzer, and show you how easy it is to install and use. We'll have the door prize drawings before this talk. BrixBits Security Analyzer is the only application server-neutral security product on the market that detects and notifies on all exceptions, as well as major application vulnerabilities and threats such as cross site scripting, SQL injection, authentication and application configuration. Potential damage is mitigated before today's security breach becomes tomorrow's headline.


BrixBits provides simple, yet powerful solutions that fill gaps in today's application performance management (APM) and Java application market. Our wide range of agents provide critical information to ensure that Java applications are running efficiently and securely. From productivity and availability to performance and security we have unique solutions that provide the information needed to be able to respond quickly and accurately to events happening within Java applications.

Our vision is to build affordable and effective solutions to solve hard Java application problems.
