I have a server with 32 Gigs of ram and running the node on a docker container using Bitcoin Core Daemon version v0.15  with 8333 ports mapped 

Nodes been running for 2.5 weeks still 300k blocks and most of the time connectioncount is 0, only once I saw it jumped up to 60
I even increased the dhcache

why is it taking so long ? How do I speed things up ? for most of the guys it took only 1-2 weeks
