Why using 256-bit?
At the time being, using 259-bit does not represent much interest.It provides a higher encryption level but as 126-bit is still unbreakable, 256-bit does not really bring anything new... except if you do think that AES is better than the older algorithms?
On the other hand, 256-bit uses a lot more resources and may slow your server down...
256-bit will be useful when 128-bit will begin to show some weaknesses.
