Alright, so, question. Why would the speed of the hash function make any difference, assuming it's a cryptographic hash? If it's faster, run it for more iterations - if it's slower, run it for less. You pick a maximum time, figure out how many iterations can be run in that time, and go from there. I would have thought that a fast hash function would be better, if anything - as it's potentially already more optimized for current hardware, which means that it's less likely that it will get faster on better hardware. I always thought it was the memory complexity of the hash function that was the difference, not speed. Makes it harder to run on GPUs / ASICs.
