I am currently downloading a large (60meg) file from a file storage site. I started the download from my Safari browser and it was only running at 40kbs so I opened up firefox and tried with that (while the original download is still running) and it is downloading at 74Kbs. Why would there be a difference of twice as fast?
I guess it is HTTP then. By that I mean downloading a file like you normally do with a web browser, as opposed to using FTP.
Maybe it was just different due to yousendit's servers -- their upload rates won't be equal all the time, even changing every few seconds. Not sure it'd change quite that much though, but otherwise I'm unsure.
they may use different http pipelining. I know with firefox you can get up to 8 ports or something at once but im not sure what the default is. I also have no idea how many you get with safari but a difference here would definitely make a difference if it is a http download
