jemalloc

jemalloc: "jemalloc is a general-purpose scalable concurrent malloc(3) implementation. There are several divergent versions of jemalloc in active use, including:

The canonical jemalloc distribution available via this website, which currently targets Linux, FreeBSD, Mac OS X, and Microsoft Windows.

FreeBSD's default system allocator. This was the first public use of jemalloc, and it is still author-maintained.

NetBSD's default system allocator (jemalloc.c).

Mozilla Firefox's allocator (source code), specifically for Microsoft Windows-related platforms, Solaris, and Linux. There is Apple Mac OS X support code as well, but it has yet to be used in a release."
