もともと deoplete.nvimを使っていたけれど、私の環境（Windows10 Vim8）だと補完候補が表示されるまで一秒程度時間がかかるため asyncomplete.vimに移りました。
そこそこ快適に使えるようになるまで試行錯誤が必要だったので、そこらへんをコメントしてみます。
全体のコードは末尾へ。
前提
- denite を使って toml で設定を書いています。
asyncomplete.vim 関連の依存関係
- asyncomplete.vim

- asyncomplete-necosyntax.vim
- Shougo/neco-syntax
- asyncomplete-necovim.vim

- Shougo/neosnippet.vim
vimrc で augroup vimrc を定義している。
augroup vimrc
autocmd!
augroup END
コメント
- 数メガのテキストファイルを扱うことがあり、そのファイルに対して補完候補の収集がされないように、指定した filetype だけで補完が動くようにしています。

autocmd vimrc FileType autohotkey,autoit,cfg,git,go,groovy,java,javascript,python,snippet,toml,vim,vb,xsl call asyncomplete#enable_for_buffer()'whitelist': ['*']:whitelistは書いていなければ['*']相当になると思ったけれど、そうならないこともあるようなのでそれぞれ書いています。
