SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Ingest and interpret pprof-based Markdown analysis generated by profiling tools (e.g., Platformatic Flame) and translate low-level CPU/Heap profiles into actionable architectural fixes that can be reasoned about by an AI.

Core Features & Use Cases

  • Profile Ingestion & Triage: Identify Top Hotspots by Self Time vs Total Time and distinguish CPU bottlenecks from memory churn.
  • Pattern Recognition: Detect anti-patterns like the Middleware Trap, N+1 Async Loop, and Hidden Latency, proposing concrete mitigations.
  • Actionable Optimization Workflow: Propose code changes with patch-level guidance and instruct the user to re-run profiling to validate hotspot shifts.

Quick Start

Feed the agent a pprof-md profile and request a prioritized list of fixes for the identified hotspots.

FAQPage Schema
How do I analyze Node.js pprof profiles to find CPU hotspots and memory churn?

Analyze Node.js pprof profiles by ingesting pprof-based Markdown data to rank hotspots by Self Time and Total Time, distinguishing CPU bottlenecks from memory allocations. The tool identifies top hotspots and proposes concrete architectural code fixes to resolve the performance regressions.

What is the best way to fix Node.js performance anti-patterns found in flame graphs?

Fix Node.js performance anti-patterns by applying pattern recognition to your pprof data to detect issues like the Middleware Trap, N+1 Async Loops, and Hidden Latency. It then proposes concrete mitigations and patch-level code changes to eliminate these specific structural bottlenecks.

Can I use this to triage Node.js memory allocations and CPU bottlenecks from Platformatic Flame?

Yes, you can triage Node.js memory allocations and CPU bottlenecks by feeding pprof-based Markdown generated by profiling tools like Platformatic Flame. The workflow ingests these profiles to distinguish CPU bottlenecks from memory churn and prioritizes fixes accordingly.

How do I get actionable code fixes from a Node.js CPU profile?

Get actionable code fixes from a Node.js CPU profile through an optimization workflow that translates low-level profile data into patch-level guidance. After ingesting the profile, it proposes concrete code changes and instructs you to re-run profiling to validate hotspot shifts.

Do I need pprof-md format data to identify Node.js performance regressions?

Yes, you need pprof-md format data to identify Node.js performance regressions. The analysis specifically ingests and interprets pprof-based Markdown to translate low-level CPU and heap profiles into actionable architectural fixes that an AI can reason about.
