Apple Notes Performance Tuning

Performance Benchmarks

Optimization Strategies

1. Limit Results

// BAD: Load all notes then slice
const all = Notes.defaultAccount.notes(); // Loads everything
const first10 = all.slice(0, 10);

// BETTER: Specify range (JXA supports this for some operations)
// Unfortunately JXA does not support server-side filtering
// Best approach: cache results locally

2. Local SQLite Cache

# Export to SQLite once, then query locally
osascript -l JavaScript scripts/export-to-sqlite.js
sqlite3 notes-cache.db "SELECT title FROM notes WHERE body LIKE '%project%'"

3. Incremental Sync

// Only process notes modified since last sync
const lastSync = new Date(fs.readFileSync(".last-sync", "utf8"));
const modified = allNotes.filter(n => n.modificationDate() > lastSync);
