The asciidoc.vim file contains some synchronization options (:syn sync). However, I've noticed that this can make Vim lag a little bit when typing each character on a fairly simple 150-line document[0] with a decently fast computer[1]. Removing those options restores Vim's responsiveness.
I'm including a patch that does that.

Turning on the syntax synchronization options (:syn sync) can make Vim very slow on some files, even those that are not very large. The highlighting still appears to be correct even without these options, so remove them to improve performance. --- vim/syntax/asciidoc.vim | 2 -- 1 file changed, 2 deletions(-) diff --git a/vim/syntax/asciidoc.vim b/vim/syntax/asciidoc.vim index 1303db7..05d40a0 100644 --- a/vim/syntax/asciidoc.vim +++ b/vim/syntax/asciidoc.vim @@ -23,8 +23,6 @@ if exists("b:current_syntax") endif syn clear -syn sync fromstart -syn sync linebreaks=100 " Run :help syn-priority to review syntax matching priority. syn keyword asciidocToDo TODO FIXME CHECK TEST XXX ZZZ DEPRECATED -- 2.1.1
