From Blind Spots to Merged PRs: Continuous Agentic Performance Optimization - May Walter, Hud
Overview
This talk addresses the challenge of silently accumulating performance issues in mature codebases, where pausing feature development for investigation is difficult. It presents a case study on integrating runtime intelligence into coding agents to enable continuous performance optimization in production. The approach involves agents analyzing real production data to identify high-return-on-investment fixes, prioritized by complexity and impact.
Who should watch
- AI engineers
- Product Managers
- Builders working with coding agents
- Those facing unpredictable performance investigation efforts
- Teams looking to integrate AI agents into the SDLC for production improvements
Key takeaways
- Performance issues in production codebases often go unaddressed due to the unpredictable effort required for investigation.
- Adding runtime intelligence to coding agents allows for continuous performance optimization by analyzing real production context.
- Agents can surface high-ROI fixes, such as N+1 queries and missing database indexes, scored by complexity and impact.
- This approach led to measurable P90 latency improvements within the first week of deployment in a real-world case study.
- Tech leads can receive actionable reports before sprint planning, enabling data-driven decisions about fixes.
- The presented solution is a production-ready integration, not just a demo or prototype, resulting in merged PRs and improved performance.
Notable quotes
*Performance issues silently pile up in mature codebases.*
*You have to put engineers on it just to find out if there's something worth fixing, and the effort is completely unpredictable.*
