Here are a few iterations of what I wrote. Since the process of old roman numerals is reductive, it is essentially an inject:
> ROMAN_DEC = [1000, 500, 100, 50, 10, 5, 1]

> ROMAN_DEC.map { |unit| x, n = n.divmod unit; x }.zip(ROMAN_ROM).map { |num, unit| unit * num }.join

Eventually I realized that inject wasn't necessary at all and the whole thing could be cleaned up to:

So, all your times except the last are basically the same and the only thing I did was massage it to be cleaner. On the last iteration, I did perform a change that actually saves you a fair amount of time and memory by avoiding String#+ in favor of Array#join. String concatination would probably fare just as well, but wouldn't be as readable imo.
My times are larger because I'm doing more looping. Your code is essentially an unwound loop and I wanted to see how it looked wound back up. It doesn't fare as well until I hit my last iteration where it finally becomes a fair balance between readable and performant. I would probably go with my last version over your last version just for readability sake (it isn't like this could will be performed billions of times a day).
