Need a fast ftp server (5mb/sec) to move 20-25 gb from one server to another.

Would like a fast ftp server (or equivalant) to move 20-25gb of data from 1 server to another. They are connected on a lan via 100mb full duplex. Any thoughts.

    FTP's a protocol... there's not going to be much difference between servers - it's all an interface thing.  What are the operating systems involved?  (Must it be FTP?)

    (The differences are going to be because of load on the systems involved and the performance specs between the two.  If you're transferring between two systems, everything's pretty much dependent on what those systems have in capabilities).

    The receiving server is a single xeon 2.66ghz processor with 1.5gb ram. The clients are 4 700mghz processor macines with 8gb ram.

    I suspect the server shouldn't have problems dishing it out, but if you want them to all download the file simultaneously, the best they are going to do is 25 Mbits each.  Which is roughly 3 MB/s.  This is purely because your lan is 100 Mb.  If you had a gigabit NIC in the server and a switch that supported at least one gigabit connection, then you would see higher speeds because each client would have a full 100 Mbit pipe to the server.  

    Also, remember, 100 Mb speeds are best case, typically, I'd suggest your more likely to see 50-80% of that speed, depending on how busy the switch is and taking into account protocol overhead.
