Only good reason i can think to mess around with it is to move it to another partition, not for any speed enhancement but to free space up on my over zealous initial root partiton size (although 20Gb has always been more than ample in the past 
). I have a small 512mb page on root, and a large page on my home partition.

The page file is a cornerstone requirement of providing a virtualised memory environment and should never be less than the size of physical memory - ideally it should be 1x to 1.5x the amount of physical memory. Anything less than 1x results in unneeded strain on the kernel memory manager, more page swapping I/O (very slow), more CPU usage and worst of all it makes possible a situation where you will get "out of memory" errors if you open a large enough application.
