Excel 将文件的每一行与第二个文件中的数千行进行比较时，提高速度

我有两个Excel文件。在第一个文件中，我有485行，在第二个文件中，有10700行。对于第一个文件中的每一行，我比较第二个文件中每一行的两个值

例如，对于第一个文件的第一行，我将其与第二个文件的10700行进行比较，并对第一个文件的每一行进行比较

我测试了第一个文件的前三行，需要五分钟

如何提高程序的速度

我有一个intel i7-6600U 2.6Ghz的16Go ram

尝试用以下内容替换主循环：

Application.Calculation = xlCalculationManual

For i = 2 To 3
    valPosaSejour = Application.Range("B" & i).Value2
    valPosaDate = Application.Range("P" & i).Value2

    For j = 2 To LastRowBio
        With WBK.Sheets("Sheet 1")
        If .Range("I" & j) = tgo Then
            valBioSejour = .Range("A" & j).Value2
            valBioDate = .Range("C" & j).Value2
            isAlbumine = tgo = .Range("C" & j).Value2
            If (valPosaSejour = valBioSejour) And (valBioDate = rngPosaDate) Then
                sht.Range("I" & i).Value = .Range("j" & j)
            End If

不要设置处理范围（在每种情况下只使用一次），只需加载值并进行比较。
