Case Studies¶
This page summarizes real optimizations discovered with CINST and validated on real Java applications.
Summary of optimization outcomes¶
CINST-reported container inefficiencies were fixed with small code changes and produced meaningful end-to-end speedups. In the reported experience:
- optimizations preserved semantics across inputs and passed project tests,
- each issue was resolved within 1-2 days by a junior graduate student,
- multiple fixes were submitted upstream, and over half were merged.
