Undoubtly, yes, this could hurt performance. But I'd happily run
simulation at half (or even tenth) speed if the result of this run
brings me insight into the doings of the code.
That said, a sensible logger would collect only the data requested, of
course, so you'd often get away with comparing a single byte.
