Slow ZSH

Slow ZSH

I have a slow loading zsh, where it sometimes takes longer than 10 seconds
to get to a prompt.

I think the problem is compinit - I've run "zsh -v" multiple times to try
and find a slow down, and that seems to be the part that it hangs on.

Is there any way to make this run faster? Is there a better way to debug
this problem?

Are you using 4.3.11-4.3.15? They have a feature enabled that causes
the path hash to be populated a bit slower. <.10 didn't have the
feature and .16+ lets you disable it and has it disabled by default.

This is on OS X Lion, so the version bundled is 4.3.15. I'm on OS X, so I
had to install a newer version using brew (4.3.17).

That seems to be helping for now. I will try this out for a while to see if
it helps.

If you're on osx you'll also want to mv /etc/zshenv /etc/zprofile

That's curious, would you mind explaining why?

/etc/zshenv on Mac OS X sets the path, which some people don't like.

If you rename /etc/zshenv to /etc/zprofile, it will only set the path
for interactive/login shells.

Not only does it set the path, but it does so with a quite slow
command (path_helper iirc). Setting the path from a *env file makes it
impossible for any instance of zsh to inherit the path from the
environment, including when you run a script.
