Vim programming editor speed

Problem is: gets slow when I add the following lines to my :

set foldmethod=syntax 
set foldlevelstart=1 
let javaScript_fold=1 " JavaScript 
let perl_fold=1 " Perl 
let php_folding=1 " PHP 
let r_syntax_folding=1 " R 
let ruby_fold=1 " Ruby 
let sh_fold_enabled=1 " sh 
let vimsyn_folding='af' " Vim script 
let xml_syntax_folding=1 " XML

Context: whilst editing a file

I think it's fair enough for it to slow down when:

... but... for it to do so everywhere?

Do you use/see the same? What could be done to ameliorate the sluggishness, if anything?

It took me a day to identify this, successfully reproduce it anywhere on my (virtual and non-) machines, eliminating candidate contributors to overall slowness by a process of binary search.

My environment

VIM - Vi IMproved 7.3 (2010 Aug 15, compiled Mar 12 2013 14:05:25)

OS X v10.8.3 (build 12D78)

v3.2.48(1)-release

set foldmethod=indent

is much faster and works more reliably and in a more predictable manner across languages than syntax.

Also, what is the point of adding " PHP after let php_folding=1?

Anyway, you should get yourself a proper Vim: the one provided with Mac OS X is both outdated and crippled. Using the latest available version may not fix your issue but it provides the best baseline for asking and providing help.

You can play with some auto commands. Turning on features depending on the type of files, vim can speed up. Example:

autocmd BufRead *.pt set filetype=xml
au FileType xml setlocal foldmethod=syntax
