Bamboo server - Slow downloads speeds

Question

Hi,   We moved Bamboo to a new Cent OS 7.2 server.  For some unknown reason we are have slow download speeds.  We have secured the server using nginx acting as a proxy/SSL.  But, even when allow download directly from Bamboo over port 8085 they are slow and time out 50% of the time.

We haven't noticed any  build issue but once the build is completed and we attempt to download it.

Thanks!

Looks like problem with limits, please, provide
