JEP 515: Ahead-of-Time Method Profiling
Summary Improve warmup time by making method-execution profiles from a previous run of an application instantly available, when the HotSpot Java Virtual Machine starts. This will enable the JIT compiler to generate native code immediately upon application startup, rather than having to wait for profiles to be collected.
Improve warmup time by making method-execution profiles from a previous run of an application instantly available, when the HotSpot Java Virtual Machine starts. We can draw simple conclusions about an application's behavior by inspecting its source code or its class files, but we will be uncertain about how it interacts with the highly dynamic Java Platform. The JIT can initially stay out of the application's way, taking its time to get the final code just right, based on the latest profiling information.
