+Buliding using tcmalloc
+-----------------------
+
+tcmalloc is a fast and space efficient implementation (for little objects)
+of malloc(). Compiling Redis with it can improve performance and memory
+usage. You can read more about it here:
+
+http://goog-perftools.sourceforge.net/doc/tcmalloc.html
+
+In order to compile Redis with tcmalloc support, install tcmalloc on your system
+and then use:
+
+    % make USE_TCMALLOC=yes
+
+Note that you can pass any other target to make, as long as you append
+USE_TCMALLOC=yes at the end.
