A Go library implementing a pool of byte buffers with anti-memory-waste protection, limiting memory loss from fragmentation to the maximum total size of concurrently used buffers. It is used by high-performance projects like fasthttp and quicktemplate.

Use cases

• reduce memory allocations in a high-throughput Go HTTP server
• reuse byte buffers to avoid garbage collection pressure
• pool buffers for fast serialization and templating workloads
• cut memory waste from buffer fragmentation in concurrent Go programs

When to choose

• your Go application allocates many short-lived byte buffers under concurrency
• you want a small, dependency-free, battle-tested buffer pool used by fasthttp
• GC pressure from buffer allocations is hurting performance

When to avoid

• you only need occasional buffer reuse where sync.Pool suffices
• your workload is single-threaded with tiny buffers and allocation cost is negligible
