I use multi_socket interface to download files from s3.
I found a weird situation that make out bandwidth(internet) too high when
so many downloading happened.

The in/out bandwidth is got from system monitor in Ubuntu, and it offers
the Network , Mem and CPU history.
in means download, out mean upload bandwidth.

It looks like this when I download, the red line is the out bandwidth. I'm
sure there's no other application transfering. ​
