I respect (and fear a little) those who intentionally utilize SIMD in their implementations, but I believe it's a bit too much of a semantic shift for 2-5x performance gain. Good news is that modern compilers are more than capable of emitting SIMD code even if original source is nothing but.
Most software's poor performance would be fixed long before SIMD comes into play. Reduce obvious DB/server round trips, bad data structure/cache locality, poor algorithm complexity, doing redundant computations, etc.
