SnapCache accelerates WordPress by providing a fast, reliable persistent object cache backed by Memcached.
It dramatically reduces database load, speeds up page generation, and improves scalability under heavy traffic.
SnapCache is designed to be safe and fast.
See the Benchmarks section for performance results.
Features
- Persistent object cache using Memcached
- Automatic prefetching of frequently accessed keys
- WP-CLI commands for inspecting and managing the cache
- Continues to operate even if Memcached is unreachable
