T Jake Luciani commented on CASSANDRA-4663:
-------------------------------------------

[~anubhavk] Can you explain what you mean by "since they will blow up 
corresponding to number of splits"

I would think the easiest thing would be to send many files contained in the 
{{StreamSession}} at once vs one at a time.
Since for each host this already contains many files.

> Streaming sends one file at a time serially.

> 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.
