Zsh startup really slow after upgrade to fedora 15

[Renato Botelho <rbgarga@xxxxxxxxx>]

Hello,

I've been using zsh for some years, first on FreeBSD and MacOSX, and now
on Linux.

After I upgrade my fedora 14 to 15, it became incredibly slow to open a new
terminal, follow my .zshrc, without comments:

Is there anything i can do to make it startup faster? Am I missing something
obvious?

Let me know if you need more data from my environment.
