Purge unused dirty pages in an order that first performs clean/dirty run defragmentation, in order to mitigate available run fragmentation. Remove the limitation that prevented purging unless at least one chunk worth of dirty pages had accumulated in an arena. This limitation was intended to avoid excessive purging for small applications, but the threshold was arbitrary, and the effect of questionable utility. Relax opt_lg_dirty_mult from 5 to 3. This compensates for increased likelihood of allocating clean runs, given the same ratio of clean:dirty runs, and reduces the potential for repeated purging in pathological large malloc/free loops that push the active:dirty page ratio just over the purge threshold. |

jemalloc is a general-purpose scalable concurrent malloc(3) implementation. This distribution is a "portable" implementation that currently targets FreeBSD, Linux, Apple OS X, and MinGW. 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/
