Transfer file by method and transfer rate

Hello !

I have a question about client/server transfer with method call.

I would like send a big file inside a server method from my client to format it and store it as a blob.

And I would like know if it’s possible to know transfer rate during this method call.

I suppose if you send a large file on the network it will be split and send as several parts. I would know when server receive each part.
