Always has been! FWIW: I haven't seen FTP as terribly slow, but then again everything I do is pretty local over high-speed networks (ie. 10G WAN). I do know you can get into the weeds with FTP for long haul with bad TCP windows kicking in, but that isn't my environment. There's plenty of projects that come and go. Nothing really has gained traction. Such as https://www.evl.uic.edu/cavern/RBUDP/Reliable%20Blast%20UDP.html http://tsunami-udp.sourceforge.net/ http://udt.sourceforge.net/ http://uftp-multicast.sourceforge.net/ There are some commercial projects as well. The discussion comes up on hackernews every now and then.
