当您开始实际使用它们时,实际的性能差异就会出现.但正如我在回答类似问题时指出的那样：RowVersion and Performance

If you’re not going use the rowVersion field for checking for updated items and instead you’re going to use it for consistency to ensure that the record isn’t updated since you last read,then this is going to be a perfectly acceptable use and will not impact.

Such As:

UPDATE MyTable SET MyField = ' @myField
WHERE Key = @key AND rowVersion = @rowVersion

因此,只检查行以确保自上次读取应用程序以来它没有更新时的性能将是微不足道的性能差异(无论如何它必须读取行来更新它).

但是,尝试使用rowversion / timestamp列作为自上次检查以来获取所有更新项目的方法时的性能将非常差.
