Git is very slow on OS X Whenever I use anything Git related on my MacBook (brand-new Macbook Pro with El Capitan), it takes almost a full minute for each command. I did a simple

GIT_TRACE=1 git stash


and got back this:

I'm primarily using Atlassian's SourceTree, but the problem also persists on the git command-line (also, so is the log I showed). Our source for hosting the code is multiple paid, private repos on GitHub.

Is there anything that I can try to speed up git operations? It doesn't seem to matter which operation it is, they are all slow.

I was told to ask this question here as opposed to Stack Overflow.
Run git gc once a while to speed up things (if you haven't set it to be automatically on)
