Insert Feature是我们在开发过程中最容易遇到的问题，如果Insert的feature个数有限，那么你也许不关注Insert的速度问题。但是数据量比较大》500个的时候，你就会发现如果使用 IFeatureClass. CreateFeature的速度基本是无法忍受的。

其实ArcObjects中提供了一个接口，可以满足快速批量插入的要求。他就是：IFeatureBuffer

使用方法如下：

        Set pFeatureBuffer = pFC.CreateFeatureBuffer
        Set pFeatureCursor = pFC.Insert(True)
        Set pFeature = pFeatureBuffer
        Set pPolyline = New Polyline
       
        'Create 100 features using FeatureBuffer and insert into a feature cursor
        For i = 0 To 99
           
            'Set the feature's shape TODO
            Set pFeature.Shape = pPolyline
           
            'Insert the feature into the feature cursor
            q = pFeatureCursor.InsertFeature(pFeatureBuffer)
        Next i
       
        'Flush the feature cursor to the database
        pFeatureCursor.Flush
