> If I use direct connection to WebHDFS from one node I have speed nearly 
> several gigabites/sec when download or upload large files. But if I use knox 
> I have ulpload/download speed only 100mbit/sec from the same node. Found that 
> knox limits speed for one https session. As a workaround I upload large files 
> through knox in parallel but it is not a good way.
> Couldn't find any configuration params that can control such behaviour. Is it 
> a code limitation?
