Discuss ideas for improving compiler performance in this issue. Break out detailed issues and use the t:performance label.

Measure

• Create a suite of compiler benchmarks
• Run these benchmarks on each merge with benchq
• Visualize the results
• Add additional profiling hooks into the compiler

Tune

• Experiment with changes to the compiler to improve performance around 30%
• Polish up these changes and apply them to 2.12.x or 2.13.x as appropriate
• Find an optimal set of JVM parameters (e.g. -XX:MaxInlineLevel=18 seems to help)
