An EXTREMELY FAST portable thread caching malloc implementation written in C for multiple threads without lock contention based on dlmalloc. Optimised for x86 and x64. Compatible with C++. Can patch itself into existing binaries on Windows.
A very high speed memory manager (aka malloc, aka heap manager), substantially faster than other fast malloc implementations tested (nedmalloc, tcmalloc, TBBMalloc, FastMM4) on small allocations in multithreaded scenarios. And some benchmarks for measuring heap performance.
One of the fastest & best dynamic memory allocators known, forked directly from GNU glibc v2.3.3 but with Windows support patched in. NOTE: nedmalloc supersedes ptmalloc2 and this project will no longer be maintained!
