If your XML files are autogenerated, chances are they do not contain a newline character at all. If this is the case, Mercurial will store a full copy even for 1-byte changes, so you probably have a 0.9GB Par1.xml revlog and a 6GB Par2.xml revlog.

I've once submitted a patch to ease this corner-case, but because I never came around to polish it, the change never made it in. If you are interested in experimenting with the patch, drop me a note.
