cacheOptimizer emerged from a practical problem in large MODX projects: the standard context cache attempted to store the resource map, and with a very large number of documents, building and clearing it became a separate performance and stability issue.

On projects with tens and hundreds of thousands of resources, this could no longer be solved by standard caching configuration. During a cache clear, MODX attempted to rebuild too large an amount of data, which could lead to lengthy operations and even corrupted cache.

cacheOptimizer was a targeted response to this limitation. It did not try to replace the entire MODX caching subsystem, but rather modified the problematic area so that a large project could continue operating within the existing platform.

This component well illustrates another aspect of Fi1osof's general engineering approach: first, use the standard architecture as far as it suits the task, and when a specific limitation becomes real, expand precisely that area rather than rebuilding the entire stack in advance.

cacheOptimizer is part of the overall Fi1osof component ecosystem. Public discussions on the component's usage have been preserved on modx.pro, including in the context of projects with 150,000 and 500,000 resources.
