It is probably dependent on how you are generating the file-ids.
Specifically, 'groupcompress' sorts on file-id, which tends to group
similar filenames together. If your file-ids are based on *path* rather
than *basename* that often shows a sizeable difference. (It puts mixed
content together, rather than putting all 'checkmark.png' files together.)

At least, Ian & I found that with some of the fastimport streams.
