The PegMedia Server has high bandwidth and can support multiple connections from many users.
Uploads usually occur at close to the maximum current bandwidth of the client's broadband connection.

Most good FTP clients allow you to configure the number of simultaneous download and upload connections. The optimum number to limit is one download and one upload.
