      Hi,
      Are there any tricks I can use to speed up Macvim's cold startup? It takes maybe a second to load on my machine, when it's called via the "mvim" executable.

      The last post I could find about speeding up about Macvim was from 2008 - https://groups.google.com/forum/#!msg/vim_mac/bEC5e4BLb-4/nkMIsfsRygUJ... has any progress been made since then, or are there any outstanding areas that could be sped up?

      Best,
      Kevin

        My copy of MacVim (snapshot 70) on 10.6.8 takes a full ten seconds to
        launch from cold (so does console Vim too). Even launching console Vim
        with no plugins & no vimrc, it takes three seconds.

        On Linux, Ubuntu 13.04 & SL 6.4 launch instantaneously whereas all the
        rest take between two to three seconds.

        All machines have the same plugins & same vimrc.

        Cheers,

        Phil...

                  For comparison: on my 2010 MacBook Air it takes 15 ms to start console
                  Vim and about 140 ms to start GUI Vim (as measured with "vim -g -u
                  NONE --startuptime start.txt"). To me that is more than fast
                  enough...

                  So I used binary search to track down the issue and narrowed it to this line in my vimrc: set rtp+=$GOROOT/misc/vim If $GOROOT is not set, vim gets very slow

                    So I used binary search to track down the issue and narrowed it to this line in my vimrc:

                    set rtp+=$GOROOT/misc/vim

                    If $GOROOT is not set, vim gets very slow (for me 'Starting GUI' takes about 5.5 seconds). Otherwise macvim boots in about half a second, which isn't great, but is fast enough for me.

                    I can produce more info if it'll be useful for debugging but you'll have to show me how.

                      Try

                      if $GOROOT != ""
                      set rtp+=$GOROOT/misc/vim
                      endif

                      Or else, use the standard directories ($HOME/.vim and $HOME/.vim/after for user-private scripts, $VIM/vimfiles and $VIM/vimfiles/after for system-wide scripts not distributed with Vim, and $VIMRUNTIME — at the moment, normally $VIM/vim74 — for ONLY the files that come with Vim). These are the 'runtimepath' default. On Unix-like OSes, $VIM is usually /usr/local/share/vim but it may vary a little from one installation to the next; one factor may be whether you compiled Vim yourself or got it from the same source as your OS.

                      One way to "have it both ways" if you don't need _different_ scripts in $GOROOT/misc/vim and $HOME/.vim is to symlink the latter to the former on installations where $GOROOT is defined.

                      Best regards,
                      Tony.

                        Thanks! I guess I'm just curious why the start time slows down so dramatically if that variable is not defined.
