The content is very interesting and useful, but the pace is fast and the content is dense. It would be good to have at least one extra day to go into more detail/spend more time on certain elements of the course.

The trainer is very well versed in his subject and takes the time to answer questions.There is a lot of theory before we get to the practical side, which reflects the trainer's expertise, but perhaps a little less the expected level of information, at least in my case.I was sometimes confused about the exercises, with a use of language that was far removed from what is done in the workplace.We need to get away from theory and think about how to use this knowledge in 'the real world'.

For an expert course I would have liked to go into more depth on the concepts and impacts of the JVM and optimisations, such as the impact of using virtual threads and the limitations in relation to the use of physical resources.
