> 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?
