+ Select this to enable LZO compression for register caches.
+ This will allow machine or CODEC drivers to compress register
+ caches in memory, reducing the memory consumption at the
+ expense of performance. If this is not present and is used
+ the system will fall back to uncompressed caches.
+
+ Usually it is safe to disable this option, where cache
+ compression in used the rbtree option will typically perform
+ better.
