Wouldn't it be possible to change this size of deltification windows, with a command-line option (for svnadmin dump) and/or an option in the config file? The gain would be quite important on some kinds of changes (typically ChangeLog update), and a dump of a revision is something that could be done once and for all, so that it would be worth to spend time on optimizing it. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <http://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <http://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
