Mesh is a drop-in replacement malloc library for C/C++ that transparently reduces memory footprint by recovering from heap fragmentation without code changes. It can be linked into applications or loaded via LD_PRELOAD.
Use cases
- reduce memory usage of C/C++ applications
- replace malloc to fix heap fragmentation
- run redis or other servers with lower memory footprint
- profile allocator behavior with MALLOCSTATS
- drop-in memory allocator for long-running services
When to choose
- your C/C++ app suffers from memory fragmentation
- you want memory savings without modifying source code
- you run long-lived services on Linux or macOS
When to avoid
- you need Windows support (still a work in progress)
- your workload has no fragmentation issues
- you need a guaranteed-performance real-time allocator
