The FTP tests regularly monitors performance of the FTP file transfers to/from a server.
The options here are mostly straightforward. Some are explained below.
FTP TRANSFER MODE
ACTIVE: "Active" mode is how FTP originally worked, and it is still supported (and occasionally required) by many servers. In active mode, the control connection is made from the FTP client but all data connections are made from the FTP server to the FTP client.
PASSIVE: In "passive" mode, both control and data connections are made from your FTP client to the FTP server.
RTT TESTS: Round Trip Time tests are used to gauge the distance between MCS and the FTP Server.
