Thank you for breaking this down -- since the author compared BigCache to the built in `map`, this collision behavior is precisely what brought on my line of thinking. Of course BigCache is faster than the builtin map -- they are completely different kinds of hash table. As malisp explains in a comment above, BigCache is a "direct mapped cache".
