  Also nedmalloc https://github.com/ned14/nedmalloc https://github.com/ned14/nedmalloc and hoard http://www.hoard.org/ http://www.hoard.org/. There is some comparison between the three here http://www.nedprod.com/programs/portable/nedmalloc/#FAQ http://www.nedprod.com/programs/portable/nedmalloc/#FAQ The following is a snippet from that FAQ Is tcmalloc better or worse than nedmalloc?... nedmalloc is about equal to tcmalloc for threadcache-only ops and substantially beats it for non-threadcache ops. nedmalloc is also written in C rather than C++ and v0.5 of tcmalloc only works on Unix systems and not win32. tcmalloc achieves its speed by never returning memory to the system - free space reclamation is one of the slowest parts of any allocator. Therefore tcmalloc should NOT be used outside long running server processes (and indeed its own docs say the same). However I am not sure if the criticism about not returning the memory is true anymore for the latest version tcmalloc.
