Yes. 3 megaBITs per second is just over 300 kiloBYTEs per second. There are 8 bits per byte, plus there's packet and protocol overhead, so a 10:1 ratio between the numbers is normal. > So, does that mean I am wasting money by going from > 768KB/s Up / 768KB/s Down to 768KB/s Up / 3MB/s > Down since I will never obtain download speeds faster > than the Upload limit of 768KB/s ??? No, if you downgraded to 768 kilobit/sec service you would expect a maximum download speed of around 75-80 kilobytes per second. -Chris -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
