Hoard

Hoard is a fast, scalable, and memory-efficient memory allocator that can speed up your applications. It’s much faster than built-in system allocators: as much as 2.5x faster than Linux, 3x faster than Windows, and 7x faster than Mac. No source code changes necessary. Cross-platform: works on Linux, Mac OS X, and Windows. Download Hoard now!

Technical information

The original Hoard algorithm is described in this technical paper; that version also inspired improvements made to the Mac OS X memory allocator. However, the modern version of Hoard has evolved considerably since its initial release, and today's Hoard is much faster.
