If you have a lot of data in there, may I suggest you (temporarily) add a unique index and
benchmark both methods? As I said, limit n,m is the last operation that gets executed, so
it requires rows 0-n to be fetched, too. On deep pages that can be quite a lot of data
needlessly fetched.
You might find that the expense of maintaining that index may be well worth the speedup
when fetching pages.
