Corentin Chary updated CASSANDRA-4663:
--------------------------------------
         Reviewer: Jason Brown
    Fix Version/s: 3.x
           Status: Patch Available  (was: Reopened)

On the systems that I've seen it looked that it was mainly the receiver that was CPU bound. I'm attaching a patch that provides a workaround for 3.X.

> This is not fast enough when someone is using SSD and may be 10G link. We should try to create multiple connections and send multiple files in parallel. 
> Current approach under utilize the link(even 1G).
> This change will improve the bootstrapping time of a node.
