Efficient memory management, including optimizing query caches and buffer pools, can help strike the right balance between memory consumption and query response times. Key parameters like the buffer pool size significantly impact efficiency by determining how much data MySQL can cache in memory for rapid access.

This parameter sets how much dedicated memory will be used by PostgreSQL for cache. If your working set of data can easily fit into your RAM, then you might want to increase the shared_buffer value to contain your entire database, so that the whole working set of data can reside in cache. wal_buffers. effective_cache_size.

Key Takeaways Redis offers complex data structures and additional features for versatile data handling, while Memcached excels in simplicity with a fast, multi-threaded architecture for basic caching needs. Redis is better suited for complex data models, and Memcached is better suited for high-throughput, string-based caching scenarios.

Only in extreme circumstances does the cost (in processor time and I-cache footprint) translate to a tangible benefit - circumstances which usually resort to hand-coded assembly anyway. It shouldn't be 10%, unless it's cache effects. And for leaf routines (which never establish a frame), this is a non-issue.
