Big RAM: How Java Developers Can Fully Exploit Massive Amounts of RAM

This session looks at the implications of the ever-increasing availability of large amounts of RAM (hundreds of gigabytes, or multiple terabytes) for Java developers and discusses techniques they can use to fully exploit these quantities of RAM. It shows evidence suggesting that some garbage-collected environments, such as JVMs, have limitations when fully utilizing such quantities of RAM. It then proposes strategies for fully exploiting large amounts of RAM when developing in Java, including use of alternative garbage collectors, off-heap memory in the JVM, open source and commercial caching solutions, and operating system caches. Code samples and performance test results are provided.
