When you get to the point where you're considering writing something in assembly, its no longer "premature" -- you are clearly in a domain which needs to process a lot of data and crunch it very efficiently. Once you're at that point, there can be quite significant gain. Fortunately, the vast majority of people, and situations, and programs, don't ever get there. And even more fortunately: very, very often when those people who *do* get to that place, they actually can use a library which has already done it and get those major performance gains without writing the assembly themselves. -- Stephen Hansen ...
