ORM增刪改查並行效能測試2

前言

上一篇《ORM增刪改查並行效能測試》出現了點小失誤，有的輸出SQL紀錄檔的程式碼沒有禁用，資料庫連線字串可能有問題。統一環境，統一程式碼後，重新寫一篇。

這次重點是並行效能測試，真不是為了diss其它ORM，開始是因為我寫的Dapper.LiteSql高並行場景下存在BUG，才寫了這個測試，經過修改優化，最好Dapper.LiteSql通過了這個測試。然後Fast.Framework的作者對它的ORM非常自信，我就好奇，是否真的有他說的這麼好，口說無憑，我就對它程序各種測試，包括這個高並行測試，剛開始Fast.Framework高並行測試也不通過，後經過作者的優化，就通過了。

本測試不偏向任何ORM，有一說一。如果測試環境或程式有問題，請指出，難免有失誤。

測試的現實意義

這兩天在對一些ORM進行效能測試(涉及SqlSugar、FreeSql、Fast.Framework、Dapper.LiteSql)，測試用的是Winform程式，別人第一眼看到我的程式，說，你這測試沒意義！
可能我的測試程式的某些地方寫的比較變態吧，但我認為有現實意義，並且網上有相關網站崩潰問題的文章，那什麼「爆高分析」，「崩潰問題」，WinDbg用的很6，那寫程式階段為什麼沒發現呢？

場景

假設WebApi(或者說網站後臺服務)正在被高並行存取，一段時間後，服務的執行緒數量達到了200正常的是類似這樣的，任務來了，就幹活：及以上，那麼.NET的執行緒池，如果執行緒處於空閒狀態，預設是20秒後釋放執行緒，假設這200多個執行緒空閒了，但是還沒有達到空閒20秒的時間，還沒有釋放，如果此時，又有大量高並行的存取，200個執行緒去運算元據庫，那就可能很危險了。

關於效能

雖然程式碼寫的可能有點變態，但我的測試不是很嚴格，也不是很規範。
效能如果不是數量級的差，問題都不大，比如一個是0.8秒，一個是1.8秒，那1.8秒的慢是慢了一點，但問題不大；但如果一個是0.8秒，一個是10秒，那10秒的這個，可能就有點問題了，即使別人用的Emit你用的反射，也不應該差這麼多。
當然了，我的測試，資料規模不大，10000條，button可能會點10次，那也才10萬資料量，在資料量方面我沒有做極端測試，我的重點不是這個，因為很少會去查100萬資料到記憶體中，就暫不討論這個。
這個測試除了大體上測試一下效能，主要就是增加了並行測試。
非並行效能測試的截圖我就不放全了，這幾個ORM有差別，但我覺得2秒3秒還是6秒甚至8秒，都問題不大的，都算差不多，都算堪用。

測試環境

資料庫及設定

測試資料庫是MySQL，版本5.7.28
MySql的連線池大小是1200

測試程式中設定的資料連線字串

Data Source=localhost;Port=3306;User ID=root;Password=123456;Initial Catalog=xxxxxx_test;Charset=utf8mb4;SslMode=none;Allow User Variables=True;

MySql.Data.dll版本

MySql.Data.dll目前用的是最新的8.0.30版本(題外話，它裡面的非同步是假非同步，把同步方法包裝成的非同步，我說怎麼反而慢了呢，真非同步要使用MySqlConnector.dll，Fast.Framework使用的是這個效能很好)。

引數化

測試的增刪改查，都是引數化的。

實體類

以SqlSugar的為例吧，幾種ORM測試用的表結構是相同的。

           public string Password {get;set;}

           [SugarColumn(ColumnName="create_userid")]
           public string CreateUserid {get;set;}

           /// <summary>
           /// Desc:建立時間
           /// Default:
           /// Nullable:False

           [SugarColumn(ColumnName="create_time")]
           public DateTime CreateTime {get;set;}

           /// Default:
           /// Nullable:True
           /// </summary>           
           [SugarColumn(ColumnName="update_userid")]
           public string UpdateUserid {get;set;}

           /// <summary>
           /// Desc:更新時間
           /// Default:
           /// Nullable:True
           /// </summary>           
           [SugarColumn(ColumnName="update_time")]
           public DateTime? UpdateTime {get;set;}

    }

除了MySql.Data.dll還參照了MySqlConnector.dll (為什麼net6？它不支援net framework)

除了MySql.Data.dll還參照了MySqlConnector.dll (為什麼net6？它不支援net framework，環境不同，所以這個測試結果供參考，就不要計較了)

Dapper.LiteSql net6

(為了和Fast.Framework對比，確實慢，慢70%左右，可能是MySqlConnector.dll的功勞，它是真非同步，只用MySql.Data.dll是假非同步)

寫在最後

我不偏向任何ORM，有一說一。

ORM的選擇，效能固然重要，但效能差一點也不影響使用，主要是為了測試有沒有硬傷，比如某個操作，一個ORM需要2秒，另一個ORM需要50秒，那50秒這個，慢了一個數量級還多，是不是有問題？再比如說某個測試，別的ORM，有耗時20秒的，有耗時30秒的，也有耗時70秒的，都問題不大，但有一個ORM，它報錯了，是不是個問題？

這次並行測試，EF和EFCore我沒有測試，因為我比較相信官方，可能它會慢一點，但因為使用者量特別多，應該不會有硬傷。有興趣的可以拿我的測試程式碼，稍微改一下測試測試EF和EFCore。

我自己寫的LiteSql，算是個歷史遺留問題，好幾年前從上家公司的DBHelper一路改過來的，除非我把它完全刪了，否則總想把它改好，這就需要測試，以保證質量。我因為寫LiteSql，學了一些東西，技術上多多少少有進步，這就是意義。
