Apify Performance Tuning

Overview

Optimize Apify Actors for speed, cost, and reliability. Covers Crawlee concurrency settings, memory profiling, proxy rotation strategies, request batching, and crawler selection for different workloads.

The workflow is a repeatable loop: measure a baseline, apply one lever, re-measure. The single highest-impact lever is usually crawler choice — swapping a browser crawler for CheerioCrawler on non-JS pages is a 5-10x speedup on its own. The full six-step walkthrough, with every code block, lives in references/implementation.md.

Prerequisites

• Existing Actor with measurable baseline performance
• Understanding of apify-sdk-patterns
• Access to Actor run stats in Apify Console
• APIFY_TOKEN in the environment for reading run stats via ApifyClient

Instructions
