fastcache

Benchmarks in the README show fastcache outperforms BigCache, standard Go maps, and sync.Map in multi-core scenarios, with higher millions of operations per second.

Its bucket-based architecture with off-heap 64KB chunks drastically reduces pointer count, preventing garbage collection pauses in large caches, as emphasized in the design philosophy.

Thread-safe design allows multiple goroutines to read and write simultaneously on a single cache instance, scaling efficiently on multi-core CPUs.

The API is designed for zero-allocation patterns, making it straightforward to use while maximizing performance, as highlighted in the documentation.

Cache state can be saved to and loaded from files using SaveToFile and LoadFromFile methods, enabling durability across application restarts.
