The default values for the bandwidth are set much too low in Collanos. If you need some more speed open up the preferences (Menu Tools, Preferences) and click on connections. In the section "Bandwith that you have (Download/Upload in KB/sec)" choose the option "Individual". Then click on apply.
Select the Advanced Bandwidth Settings and change the values:
Uploader speed limit (KB/sec): 10000
Downloader speed limit (KB/sec): 30000
Maximum uploaders run in parallel: 50
Maximum downloaders run in parallel: 50
Unless you have only a 56 k modem

you will see a significant increase in transfer speed.
