Kursbeskrivning


Do you feel like you’re on the drunkards walk randomly stumbling towards solutions to your performance issues? This is the norm for most organizations but it doesn’t have to be.
This comprehensive four day workshop will show you how to use our widely tested Java Performance Tuning Methodology (jPDM) to quickly and definitively find the root cause of your performance woes. jPDM has been proven world wide by our consultants and workshop attendees to resolve tough performance problems. Past attendees have told us that they were able to solve long standing nagging performance issues on the Monday morning return to their projects.
The course will introduce free and open source tooling that can be used immediately. Already got a fancy commercial tool? We say, all the better as this workshop will help make you more effective with them also. Looking at buying a fancy commercial tool? The workshop will help you decide which products have the features you'll need and which ones will work best for you. No tips, no tricks, just a solid, proven approach to Java performance troubleshooting that won't be obsolete with the next release. Exercises taken from real world problems designed to expose how Java and the Java Virtual Machine works.
