How to Measure FTP Transfer Speed
File Transfer Protocol (FTP) provides a relatively high-speed transfer of files over TCP/IP networks such as the Internet. FTP is commonly used to provide download availability on the Internet and in most cases is constrained or "throttled" so each FTP client is allotted a portion of the bandwidth available to the FTP server so the FTP server is available to all clients. Run the Windows Server 2008 Reliability and Performance Monitor application to confirm that each FTP client connection utilizes the expected amount of bandwidth.

Click the "Start" button on the Windows client computer and click "Computer." Type "ftp://a.b.c.d" in the address box at the top of the "Computer" window, except replace the "a.b.c.d" with the IP address of the Windows Server 2008 FTP computer, and press the "Enter" key. Browse to a 1 gigabyte file on the FTP site, right-click on the file and click "Copy." Right-click on the Windows client computer desktop and click "Paste." The 1 gigabyte file will start transferring to the Windows client computer.

Go back to the Windows Server 2008 FTP server and view the performance counters displayed for the FTP process. The "Total" column and the graph will display the amount of bandwidth being utilized by the FTP session. Repeat these steps with multiple FTP clients connected and downloading a large file in order to verify bandwidth-utilization measurements.
