Hi there,

I was wondering if anyone checked already what happens when you create a SSIS Package importing a flatfile source with the different notations to a local flat file.
I tested it with a large file and the system needed almost the same time for the import.

E.g.
Flatfile is on the C:\testdata\testfile.csv of the Server that will execute the ssis package

Does the Import via
\\servername\c$\testdata\testfile.csv
(or if you would rather would like to use a shared folder)
\\servername\testdata\testfile.csv
have the same performance then the access by
c:\testdata\testfile.csv?

If there is no disadvantage to use the network anotation then I could benefit from it, when I want to migrate the package to another server and leave the import-data on the "old" server.

Kind Regards
Christian

It seems the test you did was twice the same folder, but with different notations. The folder was each time on the local server.
If you move the SSIS package to another server, but leave the files, you'll have to transfer the data over the network, which might have some latency.

Yes, in my test the file was on the same system. That's how it should stay.

However if the network-path does not come with disadvantages then I can use it and
then have the flexibility to move it to another server IF there will be a reason what so ever.
When moving to another server I am aware that the real network might be a boddleneck.

So the key question is:
if the package and the flatfile are on the same server are there any disadvantages to use the network-path

Kind Regards
