Please be aware that this actually halves performance for Bignum#to_s that results in a String with less than 1024 characters. This case is the most common one, so I think we should look for a way to improve the performance for really big Bignums without degrading it too much for smaller ones.

I added a benchmark so we can see the numbers properly.
