---------
-By default Redis compiles and links against jemalloc under Linux, since
-glibc malloc() has memory fragmentation problems.
+Selecting a non-default memory allocator when building Redis is done by setting
+the `MALLOC` environment variable. Redis is compiled and linked against libc
+malloc by default, with the exception of jemalloc being the default on Linux
+systems. This default was picked because jemalloc has proven to have fewer
+fragmentation problems than libc malloc.
-To force a libc malloc() build use:
+To force compiling against libc malloc, use:
- % make FORCE_LIBC_MALLOC=yes
+ % make MALLOC=libc
-In all the other non Linux systems the libc malloc() is used by default.
+To compile against jemalloc on Mac OS X systems, use:
-On Mac OS X you can force a jemalloc based build using the following:

- % make USE_JEMALLOC=yes
