In my experience, thats a big NO. While there is some performance impact, in other ways it can actually be a benefit (spreading writes out to multiple pages, for example) so as with anything in regards to performance: benchmark, benchmark, benchmark. PS.: UUID's also work quite nicely to deal with certain system hiccups, specifically temporal ones. Could be thought of as something similar to the Erlang supervisor trees.
