This task involves prototyping potential performance improvements and writing JMH benchmarks to measure their impact. Prototypes will be refined if they demonstrate measurable performance gain and separate issues will be opened to individually track them; otherwise they will be put aside. We will use the profiling data from JDK-8062942 to help us determine what areas to focus on.

The issues linked below are the improvements that we are working on as part of this JEP.
