Not entirely sure about your problem.
That message is spot-on about the source of the problem, though.
_multi_parts is really slow. Since I have a mapping for completing
filenames generally via ^X^F, I've actually been satisfied with adding
the following to my startup files:
That prevents most(?) filename completion via _git, but I much prefer
that to the alternative of pegging a CPU at 100% for more than a minute
whenever I accidentally hit <Tab> after 'git co' (w/ 'co' aliased to
'checkout') in my work repo (which is much smaller than the kernel repo,
but many untracked files).
I have a branch in my local zsh repo called completion/_git/why-so-slow,
but it's been sitting dormant for a while for lack of tuits (along with
completion/_virtualbox and completion/_imagemagick).
