a) try clean
gvim -u NONE -U NONE -N "$@"

fast? => its your .vimrc or viml code

slow? Its vim fault


b) run vim, then use :gui command to start gui.

:gui slow -> vim's fault
:gui fast -> its vim startup

Vim has builtin profiling - not sure whether its that helpful in your
case though.

I would also add --no-plugins to that.

After you have performed your tests and determined it is not Vim, then most likely it is some of your plugins.

Move half into a different folder, reload.

Continue until you figure out which plugin might be responsible or of course just too many are loaded.

HTH,

The "-U NONE" is not necessary if "-u NONE" is being used.

That's spelled "--noplugin", although "--noplugins" also seems to
work.

It's not clear to me what you meant by that. "-u NONE" already
inhibits the loading of plugins.

gvim --noplugin

will start gvim with the normal vimrc files but without loading
plugins. However, if your vimrc enables filetype plugins and/or
syntax highlighting and you open a file, any filetype-dependent
plugins will still be loaded.

Gary

See
:help slow-start
:help --startuptime

Also, which version and OS, and configuration? There are some gotchas we could advise you on (such as the -X mentioned in slow-start).

I have checked that Gvim is faster without loading plugins and vimrc by this command :

gvim -u NONE -U NONE -N "$@"

So, now, i would like to call a function that is in one plugin.

Is it possible to load only one plugin and without _vimrc ?

Thanks you

let's you choose which plugins to activate easily.
It also supports loading plugins at runtime as needed.

grep its documentation for filetype which will tell you how to activate
plugins if you edit a specific filetype only.

The interesting question is how to tell vim which plugin to load.
Env vars could be used:

V_P='my-plugin' vim # start vim passing V_P env var set to my-plugin
then read $V_P inside you .vimrc and load my-plugin this way.

Of course there are more solutions. This is my (biased) recommendation.

Alternatively, you could use the tplugin script (http://www.vim.org/scripts/script.php?script_id=2917), which will define proxy commands & catch calls to undefined functions (similar to the AsNeeded plugin) in order to enable plugins only when they are needed. You have to run the :TPluginScan command first in order to enable tplugin. You can still use VAM or a similar plugin manager to download & update your plugins.
