Re: Performance issue: initial git clone causes massive repack

Nicolas Pitre [off-list ref] writes:

If for example you have a single pack because your repo is already fully 
packed, then the "packing operation" involved during a clone should 
merely copy the existing pack over with no further attempt at delta 
compression.

There's still the question if your repository has too many objects
(for example, a branch that you deleted without garbage-collecting
it). Then, sending the whole pack sends data that one may have
considered as "secret".

To me, this is a non-issue (if the content of these objects are
secret, then why are they here at all on a public server?), but I
think there were discussions here about it (can't find the right
keywords to dig the archives though), and other people may think
differently.

Jeff King's answer in [ref]
tackles this problem too.
