Where Re-transmission packet process? Slow path or Fast Path File in blocking mode

[John_Lee]

Hello,

I tested that I copied a file from server to my host while the file server was connecting that is SMB..

 I did packet capture through wireshark.

I saw re-transmission when drag and drop file from File Server as the same time,

I think the re-tranmission packet goes to the Slowpath

because File blocking's function include to slowpath

Is it right? :0

If it is true, Can you let me know what document pelase?

Thank you

Here is a document describing slow path & fast path:

If the session is in slow path, then the re-transmitted packets will also be handled in slow path.  If the session is in fast path, then the re-transmitted packets will be in fast path.
