Read the paragraph just before the one you're quoting:

"The xdelta algorithm is much faster at reconstructing older files,
and thus there's motivation to dump and reload your existing
repository. If you do this, you forcibly re-compress all repository
history using the xdelta algorithm, resulting in a noticeable speedup
in operations that ask the server to reconstruct older data..."

So you just need to dump and load.
