Slow startup time because of git lfs

[dgmora]

I've noticed that lefthook usually takes more time than I would expect to start. When adding --verbose to the 'internal' hook, I noticed that the following command is the one that is slowing things down:

git lfs pre-push origin git@...

Adding skip_lfs: true in .lefthook.yml solved the issue. I've just checked and without skip_lfs it takes maybe 4-5 extra seconds. Sometimes it felt like more.

I was wondering if there's an valid reason for it taking that long. I have git lfs, but I don't quite understand why should it cause this slowdown
