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.
Goals
Help applications warm up more quickly by shifting the collection of initial method execution profiles from production runs to training runs, conveying the profiles via the...
