XMM is a fully self-implemented third-party memory manager for Go, built on Linux mmap, that allocates and frees memory independently of Go's built-in GC. It supports building high-performance data structures like lists, trees, and hash tables while escaping GC pauses.
Use cases
- avoid Go GC pauses in high-performance services
- allocate and free memory manually in Go like C/C++
- build custom high-performance data structures in Go
- reduce GC overhead with many small memory allocations
- implement GC-free maps and slices in Go
When to choose
- your Go service suffers latency spikes from garbage collection
- you need millions of allocations per second with goroutine safety
- you want to build custom data structures outside Go's GC
When to avoid
- your workload is fine with Go's built-in allocator and GC
- you need cross-platform support beyond Linux mmap
- you want a battle-tested allocator like tcmalloc with broad community support
