With normal UI diffs, you can only get one diff at a time. Through the
API, you can get hundreds of revisions in one request. Looking up the
previous revision for each of them means hundreds of database queries,
which will kill the database.
Note: getting diffs through the API is now possible (see the "Getting
differences between revisions" thread in this list).
