Welcome to the course “Performance Optimization”. This course is designed to help you get started to understand the primers of performance affecting your application and how you can tune these primers. There could be a lot of factors that might affect the performance of your application. For example, the TCP connection parameters, web server related optimization, tools that will help for performance debugging and tuning. We will be covering these topics in this course. The application code itself can affect the performance of the application single handedly but the application code optimization is beyond the scope of this course.We will be continuously improving the course by adding more topics around performance optimization. However, we are open to your feedback. If you think some more topics around optimization should be included in the course then feel free to suggest us and we will try to create more videos on it and will append to this course.
