urandom is the faster less secure random generator. Looking at a few dd's from it, I would think it would work as well for this purpose. Instead of using isalpha and friends, just make sure the char value is between 32 and 126. That'll give you a better range of usable but non-alpha characters.
/dev/urandom and /dev/random use the same algorithm for generating random numbers, and so their speed is the same. The big difference between the two is that the random number generator keeps traccxcxcx
