Dive into the frantic world of software optimization where you assume the role of an eager Java Virtual Machine trying to outsmart the CPU and improve your application's performance. As new and complex workloads emerge, you must dynamically choose what code to compile ahead-of-time and what to set for just-in-time execution. Juggle between startup, warmup, and peak performance phases while managing the AOT cache to keep everything running smoothly. Utilize tools and commands to execute strategies against shifting workloads, boosting efficiency and breaking high scores. Will you become a master of balancing code compilation or will the workload's changes leave you in a slowdown?
