I wonder if they tried multicast. It would be strictly more efficient in terms of bandwidth (one copy per router/hop rather than all the different pieces flying back and forth) and likely less CPU. There's premade software like uftp (http://www.tcnj.edu/~bush/uftp.html http://www.tcnj.edu/~bush/uftp.html) to do this.
- moe 16y agoAmen. The NIH syndrome at twitter seems to be going strong. They just don't stop reinventing stuff, and usually poorly. In this case uftp is the time-tested solution, made precisely for this purpose (mass deployment) and provably better on all metrics (speed, bandwidth, security via SSL, complexity). The mind remains boggled...
- nullstyle 16y agoYou do realize that twitter didn't invent bittorrent, right? ;)
- alec 16y agoThey appear to have invested substantial time into integrating it with their deployment system and improving its performance for their particular network situation rather than using off-the-shelf software like uftp.
