SUBAGENT CONTEXT

This is an isolated subagent running in parallel with other NFR domain evidence audits.

Your task: Assess PERFORMANCE NFR domain only.

SUBAGENT TASK

1. Performance Evidence Audit Categories

A) Response Times:

API response times (<200ms target)
Page load times (<2s target)
Time to interactive (<3s target)

B) Throughput:

Requests per second capacity
Concurrent user support
Database query performance

C) Resource Usage:

Memory consumption
CPU utilization
Database connection pooling

D) Optimization:

Caching strategies
CDN usage
Code splitting/lazy loading
Database indexing
