Codez un logiciel

Hello im a student and I study a course called Java performance, im having difficulties to analyse and optimize the code which the professor gave me. The goal of this project is to help me profile and to see why my java project doesnt use well cpu and why gc isnt working well.. The first step of this project: I need someone who already worked with visual vm and who can give me a full report about the current performance of the application. Second step: Analyze code (4 classes only) and optimize the app to use more cpu and less memory.. I can provide full documentation and we will be working together.. If you succeed on this project, I will hire you for the next 7 exercices which I will have with my professor. Remember I need someone who know how to use visualvm and the plugin visualGC in linux. Thanks.
