Possibly, but a vanishingly small one. A user would need to be running a 32 bit version (not possible in calibre 6) and be comparing 2 books in excess of a few hundred thousand pages.
If I were the developer then doing the diffs using files would be low priority, especially if the underlying tool didn't directly support it.
FWIW: calibre keeps the entire db in memory.
@owndbycats: it converts to txt, which by definition contains only text. Where it gets the text from a layered pdf is another issue.
