ETL table from one SQL Server to another SQL Server

I would like to ETL a table from one instance of SQL Server to another instance of SQL Server. I do not want to create an SSIS package. I have tried 1) to extract the data using an External Table on the destination (i.e. I use the External Table to create a local copy e.g. with

INTO #Hello FROM MyExternalTable

). 2) Linked Server with using

* INTO #HELLO FROM MyLinkedServer.MyDB.dbo.MyTable

3) I have also used

. They all run single threaded, which I can see from the execution plans. I have not used

but it seems that I first need to save the table to a file and then read it from the file and load it. So I do not think it is the correct tool for this task. What is the fastest approch to copy a table from one SQL Server instance to another SQL Server instance?
