This is the main tracking page for JDK 15 start-up performance.

• An exhaustive list of JDK 15 start-up performance RFEs can be found at the JDK 15 Startup Dashboard
• This page include high-level discussion of key RFEs for JDK 15.
• This page may be periodically updated during the JDK 15 development cycle. New RFEs may be added, and some RFEs listed below may be deferred to subsequent JDK releases.

<h2>RFEs targeted for JDK 15</h2>

JDK-8198698: Archive Lambda classes in CDS

• Lambda proxy classes loaded during dynamic CDS archive generation are stored into the CDS archive. This avoids the dynamic generation of these classes during runtime.

JDK-8236604: Saved the linked state of well-known classes during CDS dump time

• This could potentially save about 7% of HelloWorld start-up time (3.3ms out of 43ms).

JDK-8026297: Generating AdapterHandlerEntry during CDS dump

• Preliminary result shows about 6% improvement of HelloWorld start-up time (note that this overlaps with JDK-8236604)

<h2>Investigation Tasks</h2>

(TODO) here we have investigation tasks (e.g., profiling data, prototypes) that can help us identify future optimizations. (TODO) can these be subtasks of this page?
