It depends, of course, on why it is slow. You can start vim with
the --startuptime option to get a better idea of where the slowdown
is. See ":help --startuptime".

For example, starting vim on my Cygwin system was really slow
because I wrote my vimrc and some plugins as I would for Unix, where
running external programs is really fast. I re-wrote those to make
less use of external programs.

As another example, starting vim on a remote Linux machine via ssh
and X from a local Linux machine can be slow if the connection is
slow because vim communicates with the X server and the terminal on
the local machine. I don't know what to do in that case other than
be patient or start vim with -X and forgo some of the features of X.
