Hi!
On a big repository (57000 files, 2,5 gigabytes in .git/objects), git
cherry-pick is very slow for me (v2.15.0). This is cherry-picking a
one-file change, where the file is in the same place on both branches,
and which applies cleanly (I am backporting a few fixes to a
maintenance version):
$ time git cherry-pick -x 717eb328940ca2e33f14ed27576e656327854b7b

Something is not how it should be here. The repo shares objects
(.git/objects/info/alternates) with another repository (I have run
"git gc" on both repositories).
Running strace, it seems like it is doing lstat(), open(), mmap(),
close() and munmap() on every single file in the repository, which
takes a lot of time.
I thought it was just updating the status, but "git status" returns
immediately, while cherry-picking takes several minutes for every
cherry-pick I do.
