SignInManager.PasswordSignInAsyncは、私はASP.NETのアイデンティティを使用して、自分のアプリケーションでは、多くのデータベース・アクセス

を生成します。すべてのものは、作業罰金ですが、テストで、私は次のコマンドでは、多くのデータベースを作成することがわかっアクセス： SignInManager.PasswordSignInAsync：SignInManager.PasswordSignInAsyncは、私はASP.NETのアイデンティティを使用して、自分のアプリケーションでは、多くのデータベース・アクセス

var result = await SignInManager.PasswordSignInAsync(user.UserName, model.Password, model.RememberMe, shouldLockout: true);

を性能試験を使用してアプリケーションをテストするとき、私は、この問題を確認します。テストは、ログイン要求が応答を取得するには膨大な時間が必要であることを示しています。：次の図は、ログイン要求のための性能試験の結果を示しています。

それから私は、コマンドSignInManager.PasswordSignInAsyncが実行されたときに起こるかどうか確認するために、SQL Serverプロファイラを使用します。これは、データベースアクセスの多くが生成されていることを示しています。以下は、SQL Serverプロファイラから取得されます：

私は「それが来るとして」あなたがアイデンティティの設定を使用していると仮定するつもりです。その場合、あなたはまた、おそらくEntity Frameworkのを使用することになります。

あなたの質問に答えるために：私の経験では、UserManagerの後ろに座っているUSERSTORE、SignInManagerなどは、アクションが実行される複数回アクセスされます。

私が気づいた主な問題は、彼らがこの場所でEntityFrameworkで信じられないほど遅いでした。私は自分のCustomUserStoreを作成した場合、それが劇的にログイン/ユーザーアクションのスピードを高速化することを発見しました。 は、複数の呼び出し方法にが、はるかに良い行いはまだあります。私の場合は

私は私の新しいUSERSTOREを駆動するためのマイクロORM Dapper.NETを使用。 DapperのはEntityFrameworkよりもはるかに高速クエリを実行することができます（一部のテストでは、クエリに応じて3-10倍高速 - 参照：https://www.exceptionnotfound.net/dapper-vs-entity-framework-vs-ado-net-performance-benchmarking/）
