Author: delphij Date: Wed Jun 28 04:19:54 2017 New Revision: 320431 URL: https://svnweb.freebsd.org/changeset/base/320431 Log: Chase malloc() change by removing lg_chunk malloc_conf settings. In jemalloc 5, there are no longer chunks, and as configured on FreeBSD (the "retain" option defaults to false), the mmap() requests are precisely sized for the specific needs, which means the virtual memory overhead should be lower for small applications.
