The Art of System Performance Diagnosis
The course objective is to teach system performance bottleneck diagnosis skills to enable Performance Testers to take their first step towards Performance Engineering career path.
This is a intermediate level course that helps Performance Engineers to perform systematic performance problem diagnosis, for identifying & isolating the performance bottlenecks during performance testing. Without just covering performance bottleneck analysis techniques, this course is designed to provide very detailed insights on all the technical concepts from the scratch & to teach systematic steps required to analyze & isolate the system performance bottlenecks.
This is a very detailed course that covers how 360 degree performance analysis can be carried our while carrying out performance tests by covering 15 performance bottleneck analysis techniques of various categories like test results analysis techniques (scatter plot, time series analysis, threshold analysis, outlier isolation analysis, etc) , client-side performance analysis techniques (website front end performance, mobile device performance,etc ) & server-side performance analysis techniques (code profiling, memory leak analysis, heap dump analysis, GC analysis,etc).
In overall, this course will to teach the art of performance bottleneck analysis for investigating the system performance health for web applications developed using J2EE & .NET technologies. The course also covers prevalent bottlenecks on server resources (CPU,Memory, Network & Disk) & on Web, Application & DB servers in detail. The course covers details about various diagnosis tools used while explaining the real life case studies for each performance bottleneck analysis techniques.
The target audience include Performance Testers & Performance Engineers, NFR Test Consultant & other QA professionals who are interested in performance bottleneck analysis beyond doing performance test execution. At the end of this course you will realize how holistic mindset has helped you to identify system performance bottlenecks. And now, with this mindset you will be now ready with the pre-requisite to jump onto advanced areas like Performance Modelling, Capacity sizing, etc.
Take your first step towards Performance Engineering now !
