This whitepaper explains how caching boosts Laravel application performance and scalability. By storing results of expensive operations, caching reduces server load and improves response times. Laravel supports route, query, view, and config caching, cutting redundant processing. Backends like Redis, Memcached, and DynamoDB enable flexible deployment, while drivers such as APC, File, and Database balance speed and scalability. Effective strategies include write-through, lazy loading, and read-through caching. Additional optimizations—upgrading PHP, pruning packages, updating modules, compressing images, and minifying JS/CSS—further enhance speed.
