Timings for individual instructions are a bit meaningless, as out-of-order execution and speculation on modern CPUs makes it hard to pin down the timing of anything.

I did an experiment to double the number of instructions. It slowed things down by ~10%, so increasing the number of instructions by 1% would be expected to result in a slowdown of 0.1%.

In other words, this is going to make little or no difference to performance. It does make things cleaner and simpler though, which has its own benefits.
