If you want to run multiple FTP sessions concurrently you will need to create multiple concurrent processes or threads. Each process or thread can upload one file. You can create as many concurrent processes or threads as necessary to optimize throughput.

You might want to limit the number of concurrent connections, to avoid overloading the server, network or client system. There are various modules which would help with this. You might consider LWP::Parallel::UserAgent, Parallel::ForkManager or one of the other Parallel modules, Proc::Queue, POE or others.

You should try to determine what is limiting your throughput. Creating multiple concurrent FTP sessions may not help if they all share a single limiting resource (e.g. a single network link that is at capacity). Simple manual tests can confirm that multiple concurrent sessions will improve throughput. It might be worth doing this before developing a more complex program.
