May I ask where did you get this magic number 80? And what influence on the performance the number of granted roles could possibly have? Can you provide any facts to support your assumption?

IMHO you've firstly invented an irrelevant question and then invented even more irrelevant answer for it....

My ansver to your question would be: users should be granted exactly those privileges that he needs to perform his job. No more and no less. In how many roles those privileges are spread depends on many factors. But the number of roles should have no particular influence on the performance.
