Patch 7.2.269
Patch 7.2.269
http://groups.google.co.jp/group/vim_dev/browse_thread/thread/fcce6570fc7f025c/1ab37514f5656c7b
Problem: Many people struggle to find out why Vim startup is slow.
Solution: Add the --startuptime command line flag.
Files: runtime/doc/starting.txt, src/globals.h, src/feature.h,
src/main.c, src/macros.h
--startuptime={fname} *--startuptime*
During startup write timing messages to the file {fname}.
This can be used to find out where time is spent while loading
your .vimrc and plugins.
When {fname} already exists new messages are appended.
{only when compiled with this feature}
地味だけどこれは大きい修正だと思う。これまで遅いvimscriptを見つけ出すには、時間を計測出来る様なスクリプト書いて内部で":source"させるとか、重そうなのを勘で選んでpluginから外してみるとかと言った人間臭いソリューションしかなかったんですが、これで楽に遅いvimscriptを見つけ出せる。
起動時に"--startuptime"オプションを付けるだけです。
# vim --startuptime=foo.log
こんな感じに出力するファイル名を指定すると、以下のファイル(foo.log)が生成される

これを見るとvimrcと、codepad.vimの読み込みが遅い事が一目瞭然である。ちなみにcodepad.vimを外して起動すると

30msも減っている事が確認出来る。実はcodpad.vimは内部でpythonインタプリタを呼び出しており、これがvimの起動を遅くしている原因となっています。vimrc内部でどの部分が遅いかについては、個々に見ていくしか無いのだけれど、ちょっと最近vimの起動が遅いのよねぇ...奥さん...って人には持って来いだと思う。
ちなみに入ったばかりなpatchなので、試すにはソースからビルドするしか方法はありませんが、プロファイル用にvimをビルドしてみる...ってのもありかもしれませんね。
