# AppFolio Performance Tuning ## Overview AppFolio's property management API handles bulk tenant queries, property portfolio pagination, and work order batch processing. Large portfolios with thousands of units generate heavy read traffic on listing endpoints. Optimizing cache lifetimes for slow-changing property data, batching work order updates, and pooling HTTP connections reduces API call volume by 60-80% and cuts dashboard load times from seconds to sub-second. ## Caching Strategy ```typescript const cache = new Map<string, { data: any; expiry: number }>(); const TTL = { properties: 300_000, tenants: 120_000, units: 300_000, workOrders: 60_000 }; async function cached(key: string, ttlKey: keyof typeof TTL, fn: () => Promise<any>) { const entry = cache.get(key); if (entry && entry.expiry > Date.now()) return entry.data; const data = await fn(); cache.set(key, { data, expiry: Date.now() + TTL[ttlKey] }); return data; } ``` ## Batch Operations ```typescript async function batchWorkOrders(client: any, ids: string[], batchSize = 25) { const results = []; for (let i = 0; i < ids.length; i += batchSize) { const batch = ids.slice(i, i + batchSize); const res = await Promise.all(batch.map(id => client.http.get(`/work_orders/${id}`))); results.push(...res.map(r => r.data)); if (i + batchSize < ids.length) await new Promise(r => setTimeout(r, 200)); } return results; } ``` ## Connection Pooling ```typescript import { Agent } from 'https'; con...
