The result on a fresh clone of the kernel repo (158152 revs in the
manifest):
old file size:    703584066 bytes ( 671.0 MiB)
new file size:    177162218 bytes ( 169.0 MiB)
shrinkage: 74.8% (4.0x)

I didn't clone the whole repo, so I don't know how big it is, but I
think the manifest is 1/2 or 1/3 of it. It would be nice if someone
could check.

cheers,

Benoit
