Access to the cache requires + no locks and therefore significantly accelerates the fast path to allocate + and free small amounts of memory. Refilling an empty cache requires locking + the underlying arena. Performance measurements show significant gains in a + wide variety of user workloads. Workloads were captured using a special + instrumented malloc and analyzed with a malloc simulator. Contributed by + DJ Delorie with the help of Florian Weimer, and Carlos O'Donell. + * Unicode 10.0.0 Support: Character encoding, character type info, and transliteration tables are all updated to Unicode 10.0.0, using generator scripts contributed by Mike FABIAN (Red Hat). |
