+Buliding using tcmalloc
+-----------------------
+
+tcmalloc is a fast and space efficient implementation of malloc(). Compiling
+Redis with it can improve performances and memeory 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.
