apify-performance-tuning

Optimize Apify Actor performance: crawl speed, memory usage, concurrency, and proxy rotation. Use when Actors are slow, consuming too much memory, or being blocked by target sites, or when a crawl is too expensive per run. Trigger with "apify performance", "optimize apify actor", "apify slow", "crawlee concurrency", "apify memory tuning", "scraper performance".

# 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](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`
