String字节数一长操作就慢，如何解决

String字节数一长操作就慢，怎么解决？
我是用Str   =   Str   &   "…… "
的方法来生成静态页面的但是Str字节一多操作就会慢上十倍之多，有什么办法解决吗？

用stream. set stream = Server.CreateObject( "Adodb.Stream ") stream.Open stream.WriteText( "DSFSFF ") stream.WriteText( "BBBBBBBBBBBBBB ") stream.WriteText( "CCCCCCCCC ") Dim iLength iLength = stream.Position stream.Position = 0 Response.Write(stream.ReadText(iLength )) stream.Close
