非常に遅いページ - クエリ数を最適化する方法

Question

編集12/19/2011

もう一度ありがとうIjaas。日の順序を除いて、すべてがうまくいっています。公開順で日のグループを並べ替えています。古い投稿のmeta_keyの日付が新しい場合、古いmeta_keyを持つ新しい公開投稿の前になります。ある日のイベントは正しくソートされますが、日はソートされません。

何か考えがありますか？

これが私が使っている現在のコードです。

カスタム投稿タイプをループし、meta_boxesに入力された日付でソートするページがあります。以前は妥当な速度で動作していたようですが、現在は非常に遅いです。私が私の質問とphp要求の順序でしている論理的な間違いが多分あるかもしれませんが、私はそれを最適化する方法を知りません。

これがページにロードされるコードです。

見やすくするためにPastebinの*オリジナル*コードにリンクします。 Pastebinコード

これは、投稿のメタデータを作成するfunctions.phpのコードです。このコードセクションのペーストビンへのリンク： メタボックスコード

前もって感謝します。

編集12/14/2011 - オリジナルのコードを以下の例に置き換えました。私は正しい方向に進んでいますか？オリジナルコードはまだ Pastebin Link から入手できます。

私はそれが以下のこのセクションにあることをかなり確信しています、なぜなら私が "Upcoming"ループを出すときにページがスピードアップするからです。何がおかしいのですか？

遅れてしまい申し訳ありません。これは、今日から10日後までの間に投稿を検索し、それらを順番に並べ替えて表示する要約クエリです。

理論的には動作するはずですが、エラーが発生したかどうかを教えてください。

私が見る2つのことが、これをスピードアップする可能性が非常に高いです。

最初にWP Queryでネイティブ時間パラメーターを使用してから、カスタムの "もの"を実行します。 http://codex.wordpress.org/Class_Reference/WP_Query#Time_Parameters

get_post_customの代わりにget_post_metaを使用してください。 http://codex.wordpress.org/Function_Reference/get_post_custom
