Currently, hugepages aware allocator backend works together with classic one as a fallback for not yet supported allocations. When background threads are enabled wake up time for classic interfere with hpa as there were no checks inside hpa purging logic to check if we are not purging too frequently. If background thread is running and `hpa_should_purge` returns true, then we will purge, even if we purged less than hpa_min_purge_interval_ms ago.
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.
