rsync transfer efficiency

[Li, Junru(Christina)]

Hi,

Does anyone have the data of the rsync transfer speed vs. other tools like ftp?
Or where is the place to find such information that compare the transfer speed
between different tools?

If I were to transfer a single large file, say 500Mega Byte, previously
non-existent on the remote host, what would be the fastest tool I can choose for
transfer?

Thanks,
Christina Li
