Performance
Measure before changing algorithms.
- Python: time the function; don't rewrite to Rust unprompted.
- SQL:
db_explainon the Database MCP. - Android:
android_profile(meminfo/gfxinfo). - Web: fewer assets; don't add a bundler for three files.
- Avoid N+1 I/O; batch when evidence shows it matters.
If it's fast enough for the stated load, stop.
