Java Application Design Practices to Avoid When Dealing with Sub-100-Millisecond SLAs

The perception of the Java language as being slow is changing, and more and more customers are using Java for many latency-sensitive applications. Many applications are delivering sub-100-millisecond SLAs most of the time, but delivering them consistently for complex application has always been a challenge. For the last two years, this session's speakers have been working on a complex Java 7 enterprise benchmark that can be deployed across clusters and must scale well while maintaining a certain SLA. During this process, they have identified several design/coding practices that affect throughput/SLAs and have identified and evaluated several solutions that can help other users design/code applications delivering better and consistent throughput/SLAs.
