I've put the timings on http://www.xbc.nu/svn/Xdelta_Performace.html.

There's no doubt that the increase in repository size is more than
compensated by the increase in undeltification speed. With Peter's
patch, this now holds for FSFS as well as BDB.

When comparing both speed and repository size, BDB still leads in this
particular test (3.6 times faster vs. 2.3 times larger repo).
