Hi,
i've recently reinstalled a fresh system (fc20-beta) on my workstation
and observing a big slowdown on git cherry-pick operation (git-1.8.4.2-1).
the previous centos installation with an old git version works faster
(few seconds per cherry pick). now the same operation takes >1 min.
my git repo isn't very big[1] but it's checked out on the linear lvm
where random i/o generally hurts and strace shows that current git version
performs 2x{lstat}+1x{open,read,close} [2] on whole checkout before
cherry-pick. there is also a .gitattributes searching on all levels
which doing another tons of i/o. looks like git-status on action but
why on whole repo while cherry-pick touches limited set of files?
is it a bug or feature?
BR,
Paweł.
please CC me on reply.
