Author: trasz Date: Tue Mar 31 13:48:06 2020 New Revision: 359481 URL: https://svnweb.freebsd.org/changeset/base/359481 Log: Make jemalloc(3) default to retain:true on 64-bit platforms, like it already does on Linux and OSX. This results in significantly fewer calls to mmap(2). This should result in a small reduction in system CPU time and improved superpage usage.
