从表单上传时使用带宽

Question

I need to know how much bandwidth is used when uploading a file through a form.

Let me explain a bit more easily. I have a file containing a upload form that is hosted on a web host. When the user uploads a file it is uploaded through this form and to another server through FTP, so basically I'm creating a FTP connection inside the PHP file that is stored on a web host.

How much bandwidth is used if I upload a 100MB file? And is it the receiving server (the server we upload to through FTP in PHP file), is it the web host (where we are hosting the PHP file that opens the FTP connection) or is it both that uses the bandwidth needed to upload a 100MB file?

Answer 1

When you use 100MB of bandwidth (transfer to first server) and another 100MB of bandwidth (transfer to another server), that's 200MB of bandwidth. 100MB download, 100MB upload. Sometimes your provider will bill those separately.

100 + 100 = 200. It really is that simple.

(Note that there is overhead in all cases, but not a ton.)
