fasp vs. FTP

fasp vs. FTP on Intercontinental Links

fasp's throughput advantage over FTP is more pronounced on an intercontinental transfer. At a packet loss rate of 2% and latency of 150ms, an FTP file transfer between continents runs at 700 kbps, and can drop to a crawl during periods of high congestion. fasp maintains stable throughput at link capacity in around-the-world file transfers. Using fasp file transport, a 1-gigabyte data transfer on a 10 Mbps link at 2% loss will run consistently at 9.9 Mbps, and finish in under 15 minutes, regardless of distance. On a 45 Mbps link, the transfer finishes in 3.3 minutes. An FTP transfer under the same conditions takes several hours, and may terminate prematurely.
