I find that hard to believe. That operation is disk bound, or if the file is in disk cache then it is memory bound. 

I am not saying that this is the bottleneck.  But saving say 1-2/10ths of a second when loading a large file is not insignificant. Especially if it can be easily done.

I doubt you will achieve better than 0.1% improvement though. That said, I do want the compiler to do a better job producing efficient code. It shouldn't be getting in our way.
