If you're using FSFS as the back-end file system (instead of Berkley
DB), each revision is stored in a single file. Since a revision might
have a few hundred / thousand files committed as part of it, you could
indeed have a few hundred / thousand files in one gigantic file.

There's also delta code that comes into play (the file for revision #123
will only have the changes that make things different compared to a
previous revision). And SVN uses a fairly good algorithm for choosing
which previous revision to base off of for the new revision.

(I'd imagine that the SVN Book or the website might go into more detail.
  I don't worry overly much about it.)
