运行下面的代码令人失望的2分10秒.第二次运行需要6.5分钟.这个问题与this one有关

Private Sub RunTest()
    Dim sw As New Stopwatch
        sw.Restart()
        Using db As New TestDB
            db.Configuration.AutoDetectChangesEnabled = False
            For n = 1 To 100
                For m = 1 To 100
                    db.Tops.Add(New Top)
                Next
            Next
            db.SaveChanges()
        End Using
        MsgBox(sw.Elapsed.ToString)
    End Sub

实体：

Public Class Top
    Public Sub New()
        MyBase.New()
        One = "arerjlwkerjglwejrglwergoiwerhgiowehrowerlwelfvbwlervbowerghpiweurhgpiwuerviiervljwebbrlvjnepvjnweprvupiweurv"
        Two = "w;lrjgwwergkjwervgjwelrgjhwelghlwekglwergiuwehrgwjergjwervgjwerjgnwekrngpwergjpowergllwejrnglkwerngpoierhpiiuewrpjwenrwenrv;lwenrvkjernpgpsrvpi"

    End Sub

    'ID'
    Public Property ID As Integer

    'NATIVE PROPERTIES'
    Public Overridable Property One As String
    Public Overridable Property Two As String

    'NAVIGATION PROPERTIES'

End Class

在第二级交互中移动Using块并调用SaveChanges会使它变得更糟.

TestDB只是继承了DBContext而没有任何进一步的配置.当我禁用Top.ID属性的数据库生成并自己提供ID时,性能提高了30倍.这个问题使得在sql Server Compact中使用数据库生成的ID变得不可能.除了使用客户端生成的ID之外,还有其他解决方案吗？
