大きくて遅いストアド プロシージャを継承しましたが、悪夢に見舞われています。
デスクトップにSQL Server 2008をインストールし、本番データベースのコピーを使用しています。私はSSMSからすべてを実行しており、ストレートSQLとSPを試しました。Sp と SQL の時間はほぼ同じなので、過度に心配する必要はありません。気になるのは、ローカルとサーバーの時間です。
Local:
2Ghz dual-core
4Gb RAM
SQL 2008 Sp1
Microsoft SQL Server 2008 R2 (SP1) - 10.50.2500.0 (Intel X86)
Enterprise Edition on Windows NT 6.1 <X86> (Build 7601: Service Pack 1)
Server:
2Ghz dual-core
4Gb RAM
Microsoft SQL Server 2008 (SP1) - 10.0.2573.0 (X64)
Standard Edition (64-bit) on Windows NT 5.2 <X64> (Build 3790: Service Pack 2) (VM)
sproc を「ローカルで」実行すると、完了するまでに約 6 秒かかります。
サーバーに対して sproc を実行すると、完了するまでに約 25 分かかります!!!
[合計インサート = 45,500]
できる限り SP を調整し、パラメーター スニッフィングを回避しようとしましたが、ほぼ同等のマシンでこれが非常に遅くなる理由がわかりません (SQL Server のバージョンがわずかに異なることはわかっていますが、なぜそうなるのかわかりません)。そんなに違いますか？）
SP が素晴らしいものではないことはわかっていますが、ローカルで 6 秒で実行される場合、完全なパンツではありません。サーバー上で 60 秒かかった場合でも問題ありません。この SP には 15 回の呼び出しがあります...したがって、15*0:06 は受け入れられます...15*25:00 は受け入れられません!
これらの SP が実行されていないときのサーバーの負荷はかなり低く、進行中のときは約 50% の CPU (1 コア 100%?) です。ローカルで CPU が 25% を超えることはありません。
SP全体を投稿するためのApols ...しかし、物事を改善するために設定できるオプションがある場合に、それが何をしているのかを示す方法が他にわかりません:(
