Obviously this greatly depends on your ISP link speed. For example the mylinks module (approx 220KB) would take 30-35 seconds over a 56Kb link but take 5-6 seconds over a 300Kb link (equiv. to many high speed links). Wf-downloads (a download module) is approx. 3X the size so you can multiply the above numbers by 3 for estimates.
This of course, as previously stated, assumes you have an efficient ftp program, there are minimal dropped packets/connections, etc...
