    Performance Aspects

    In the first place various aspects of performance in general are treated, such as perceived performance and memory footprint and then aspects of Java performance in particular such as the hotspot JVM and garbage collection.


    Next attention is paid to the different benchmarks for Java and the various phases of the performance process such as performance monitoring, profiling and tuning. Also a number of specific performance techniques that can be applied to Java code are discussed.

    API Performance

    The performance impact of various constructs in the Java language and various classes of the Java API are discussed as well.


    Furthermore, you learn how to deal with performance tools such as a profiler in order to identify performance bottlenecks. In this respect attention is paid to profiling points, time measurements and the detection of memory leaks. Stress testing Web Applications is discussed as well.

    JDBC Performance

    Finally, special attention goes to performance issues with JDBC and performance in a Java EE environment. Herewith the configuration of pools, caches and the use of load balancing and clustering techniques are treated.
