When tiny size class support was first added, it was intended to support truly tiny size classes (even 2 bytes). However, this wasn't very useful in practice, so the minimum tiny size class has been limited to sizeof(void *) for a long time now. This is too small to be standards compliant, but other commonly used malloc implementations do not even bother using a 16-byte quantum on systems with vector units (SSE2+, AltiVEC, etc.). As such, it is safe in practice to support an 8-byte tiny size class on 64-bit systems that support 16-byte types. |

jemalloc is a general-purpose scalable concurrent malloc(3) implementation. This distribution is a stand-alone "portable" implementation that currently targets Linux and Apple OS X. jemalloc is included as the default allocator in the FreeBSD and NetBSD operating systems, and it is used by the Mozilla Firefox web browser on Microsoft Windows-related platforms. Depending on your needs, one of the other divergent versions may suit your needs better than this distribution. The COPYING file contains copyright and licensing information. The INSTALL file contains information on how to configure, build, and install jemalloc. The ChangeLog file contains a brief summary of changes for each release. URL: http://www.canonware.com/jemalloc/
