Is there a significant time difference in computing the SHA1 hash of 40 bytes versus say, 128 bytes?

128 bytes is not "large". I was thinking more along the lines of megabyte+. There is no question that it will slow down hash computations, because you would need to process more data. The question is, can you efficiently parallellize this in a commodity hardware (GPUs)?
