Hi Parminder, 1. The first level of code optimization should be in hands of the developer as the developer must have the basic understanding of requirement to best utilize the existing features, for example choosing best suitable data structures for storing and fast retrieval of data in any scenario. 2. The second level of optimization will be in choosing the development IDE, as it provides a lot of built in capabilities in identifying the best/worst code blocks like dead code. 3. And finally with the help of code optimization tools like Sonar, executing these over the custom code packages will detect a lot of things like developer mistakes due to non compliance of the industry standards, memory leaks and any sort of security vulnerabilities and etc. -Manikanta read less
