This mallctl accepts an arena_config_t structure which can be used to customize the behavior of the arena. Right now it contains extent_hooks and a new option, metadata_use_hooks, which controls whether the extent hooks are also used for metadata allocation. The medata_use_hooks option has two main use cases: 1. In heterogeneous memory systems, to avoid metadata being placed on potentially slower memory. 2. Avoiding virtual memory from being leaked as a result of metadata allocation failure originating in an extent hook. |

jemalloc is a general purpose malloc(3) implementation that emphasizes fragmentation avoidance and scalable concurrency support. jemalloc first came into use as the FreeBSD libc allocator in 2005, and since then it has found its way into numerous applications that rely on its predictable behavior. In 2010 jemalloc development efforts broadened to include developer support features such as heap profiling and extensive monitoring/tuning hooks. Modern jemalloc releases continue to be integrated back into FreeBSD, and therefore versatility remains critical. Ongoing development efforts trend toward making jemalloc among the best allocators for a broad range of demanding applications, and eliminating/mitigating weaknesses that have practical repercussions for real world applications. 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://jemalloc.net/
