Zsh startup really slow after upgrade to fedora 15

Zsh startup really slow after upgrade to fedora 15

[Renato Botelho]

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.

Nothing jumps out.  Does it take a long time only when opening a
terminal, or does it also take a long time if you just run "zsh" (or
also try "zsh -l") from the command line of an existing terminal?

If it's slow in one of those circumstances, run again with the -x
option and look for delays.

Fedora does appear to have upgraded from 4.3.10 to 4.3.11 with F15.
I wouldn't have expected that by itself to make a difference but it
is possible that the shell startup is now loading more or different
/etc/profile.d stuff.

You might try some of the startup-time suggestions made recently on
this list, such as "unsetopt hashcmds hashdirs" in your ~/.zshenv to
put off scanning everything in your $path.

We solved this on irc, it turned out to be that group lookup thing in
compaudit you fixed/worked around the other week. I asked him to send
a followup mail but i guess he didn't get around to it yet.

Curious that upgrading to Fedora 15 would cause that.  I would expect
it only to occur in a networked environment.  It is possible that F15
has the networked version of getent enabled by default now, and the
long delay is because it's waiting for a connection to a non-existent
server to time out?
