Performance Tuning & Optimization

Welcome to Redis performance tuning! Optimizing Redis ensures your applications run fast and efficiently. We'll cover server configuration, client usage, and data modeling.

A well-tuned Redis instance can handle massive loads, while a poorly configured one can become a bottleneck, slowing down your entire application.

Setting maxmemory is crucial. This limits how much RAM Redis can use, preventing your server from running out of memory. When the limit is reached, Redis uses an eviction policy.

• maxmemory <bytes>: Sets the maximum memory Redis will use.
• maxmemory-policy <policy>: Defines what happens when memory is full (e.g., noeviction, allkeys-lru).

Choose a policy that fits your data access patterns and how you prioritize data.
