  • Course Java Performance Improvement : Content

    The course Java Performance Improvement will teach you how to analyze and improve the performance of Java applications.

    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.

    Course Forms

    All our courses are classroom courses in which the students are guided through the material on the basis of an experienced trainer with in-depth material knowledge. Theory is always interspersed with exercises.


    We also do custom classes and then adjust the course content to your wishes. On request we will also discuss your practical cases.

    Course times

    The course times are from 9.30 to 16.30. But we are flexible in this. Sometimes people have to bring children to the daycare and other times are more convenient for them. In good consultation we can then agree on different course times.


    We take care of the computers on which the course can be held. The software required for the course has already been installed on these computers. You do not have to bring a laptop to participate in the course. If you prefer to work on your own laptop, you can take it with you if you wish. The required software is then installed at the start of the course.


    Our courses are generally given with Open Source software such as Eclipse, IntelliJ, Tomcat, Pycharm, Anaconda and Netbeans. You will receive the digital course material to take home after the course.


    The course includes lunch that we use in a restaurant within walking distance of the course room.


    The courses are planned at various places in the country. A course takes place at a location if at least 3 people register for that location. If there are registrations for different locations, the course will take place at our main location, Houten which is just below Utrecht. A course at our main location also takes place with 2 registrations and regularly with 1 registration. And we also do courses at the customer’s location if they appreciate that.


    At the end of each course, participants are requested to evaluate the course in terms of course content, course material, trainer and location. The evaluation form can be found at https://www.klantenvertellen.nl/reviews/1039545/spiraltrain?lang=en. The evaluations of previous participants and previous courses can also be found there.

It is not allowed to publish the course information, the information sheet, in written or digital form without the explicit permission of SpiralTrain. The course content is to be understood as the description of the course content in sentences as well as the division of the course into modules and topics in the modules.
