這篇文章受大家邀請，與 SqlSugar 做一次簡單的性能測試對比。主要針對插入、批量插入、批量更新、讀取性能的測試；

測試環境

• .net core 2.2
• FreeSql 0.3.17

• sqlSugarCore 4.9.9.3

• sqlserver 14.00.1000 Express、mysql 5.6

測試項目

以 console 程序，創建步驟：

1、dotnet new console

2、dotnet add package FreeSql

3、dotnet add package sqlSugarCore

編碼的過程

這個錯誤來自 sugar 創建數據庫的時候，實體定義如下：

sugar的沒有同步上來。

暫時先用 freesql 幫 sugar 創建了表。。。創建完後如下：

運行時又出現如下錯誤：

需要加一堆 IsIgnore

是的，還在報錯，最終原因是我傳入的 songs 是 IEnumerable，然後接受的參數類型正常應該是 Song[]，希望作者看到了可以改進。

以 SqlServer 作為目標庫，測試結果

以 MySql 作為目標庫，測試結果

結束語

然而上面提到的批量更新，今天先到這吧。下次有興致了再測試。

其他庫我就不測試了，謝謝觀看！請求獻上寶貴的一星。
