-By default Redis compiles and links against jemalloc under Linux, since

+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.
