Vim hanging after parsing .vimrc (even a blank one) file on Solaris 10

I am having a problem with vim 7.2 hanging (for about 10 seconds) after it parses the .vimrc file. I had a similar issue in the past with tcsh on linux, but it was resolved by settin开发者_StackOverflow中文版g TERM to xterm-color. The same does not resolve the issue here. Any idea what may be causing this?

Does a vim -X make any difference (as I suspect you're not running gvim) ?

Otherwise, a lot of plugins may cause this. Or plugins that hang on some operations.

You can try starting vim with -u NONE to disable reading .vimrc, -U NONE to disable .gvimrc, and the --noplugin option disables loading of plugins, see if this helps.
