dein.vimの闇の力を利用し、起動時間を100ms近く縮めた話

どうも。
NeovimにFloating Windowが入って、色々浮かせたい今日このごろです。

私、Vimプラグインを100個以上入れているのですが、
プラグインを追加する場合は、明確な理由なく、
「あ、これPythonでしか使わんから、遅延ロード！」
「あ、これとりあえず、通常ロードで〜」
ってな感じでした。

ふと、闇の力の一部である、遅延ロードをちゃんと利用したらどれだけ起動時間が、早くなるのか気になりました。

**闇の呪文「チエン」**を使って起動時間を高速化してみます！


## 実行環境（2019/04/10現在）
とりあえず、環境ぺたっと！
### PC
- PC: MacBook Pro (Retina, 13-inch, Early 2015)
- CPU: 3.1GHz Intel Core i7
- MEM: 16GB 1867 MHz DDR3

### Neovim バージョン
- NVIM v0.4.0-569-g9daa7d997

### 利用ベンチマーク
https://github.com/rhysd/vim-startuptime
deinによるキャッシュ済みの状態でベンチマーク実行

### 「チエン」実行前と実行後の差分
https://github.com/deresmos/deres.vimrc/commit/05917625f1271a0aba28f995a0fb15e9a55fad26
※コードが、かおすちゃん状態（あばばばばば〜〜）なので整理したいです。

## チエン前

チエンってないプラグイン数：80個
チエンってるプラグイン数：43個
合計：123個

自分ってかなりプラグイン入れてるんですね。（整理したい）

### 測定！

```bash
vim-startuptime -count 30 -vimpath nvim hello > before_nvim.txt
```

平均268msぐらいなんですね。速い人は、100ms切ってるんですかね。
てか、100個以上プラグイン入れててこの速度はやゔぁいな。

<details><summary>**結果詳細はここ！**</summary><div>
init.vimとかが遅いので、ここらへんのスクリプト調整すると速くなりそうですね。（また、別の機会に・・・）

## まとめ
遅延ロードを設定することで、100ms近く（35%の削減）ができました！
まだまだ、チューニングしがいがありそうなので、さらに高速化を目指してみます！
みなさんの高速化ナレッジあれば、何卒ご教授よろしくお願いいたします！
