This updates the configuration script to set the default page size to 64KiB on Aarch64 Linux. This is motivated by compatibility as a build configured for a 64KiB page will work on kernels that use the smaller 4KiB or 16KiB pages, whereas the reverse is not true. To make the configured page size setting more visible, the script now displays the page size when printing the configuration results. Users that want to override the page size in to choose a smaller value can still do so with the --with-lg-pagesize configuration option.
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: https://jemalloc.net/
