Performance was measured over link rates of 2 megabits/sec and 20 megabits/sec
with ping times from 66 millisec (within a continent) through 200 milliseconds
(between continents) to 600 milliseconds (satellite link).
Test conditions included packet loss rates from .001 (one in a thousand) to .01
(one in a hundred). These are typical losses found in long-haul
Internet Protocol (IP) links.
Gigabyte Express T2 is from 4X to 40X as fast as FTP when compared over 20 megabit links.
Gigabyte Express T1 is from 1.5X to 8X as fast as FTP when compared over 2 megabit links with
200 millisec and 600 millisec ping times.
