+  When APC is compiled with mmap support (Memory Mapping), it will use only one 
+  memory segment, unlike when APC is built with SHM (SysV Shared Memory) support 
+  that uses multiple memory segments. MMAP does not have a maximum limit like SHM 
+  does in <literal>/proc/sys/kernel/shmmax</literal>. In general MMAP support is 
+  recommeded because it will reclaim the memory faster when the webserver is 
+  restarted and all in all reduces memory allocation impact at startup.
