+      This option reduces the latency of the kernel when reacting to
+      real-time or interactive events by allowing a low priority process to
+      be preempted even if it is in kernel mode executing a system call.
+      This allows applications to run more reliably even when the system is
+      under load.
+

controller window

+      Allow the slab memory allocator to keep chains for very large
+      memory sizes - up to 32MB. You may need this if your system has
+      a lot of RAM, and you need to able to allocate very large
+      contiguous chunks. If unsure, say N.
