sabnzbd in Docker in ubuntu vm on proxmox... destined to be slow?

Hello!
I may not be the only person experiencing this and this may end up being a C++/Python debate - but I wanted to just confirm I am not missing something here.
Long story - I have a Proxmox host running Ubuntu VM which is running a bunch of docker containers including sabnzbd and nzbget. I recently decided to move away from nzbget because, while getting close to 130 mb/s (1040 mbit/s) on a 187 mb/s (1500 mbit/s) connection, it has a crazy memory leak which can cause a download to slow down to a crawl to about 5-6 mbit/s until I restart the container.
With sabnzbd, however, I can only get, consistently between 45-50 mb/s. When doing the speed test within sab, it shows bandwidth of 35 mb/s and pystone score of 80-88k... this is a Xeon-D 1528 6 core and the VM has 6 cores assigned to it; the bare metal score is way higher. But - what's even more interesting is that recently, I noticed that even in sab, my downloads slow down to 5-6 mb/s, especially when I try to download something over 15 GB.
Storage wise - I am running an SAS3 (12 gbit) based ZFS mirrored and stripped pool (i.e. RAID10 equivalent); it's plenty fast - with download folder speed being over 650 mb/s.
So - what am I missing here? I am kinda of resigned to the fact I may have speeds in the mid 50's, but why the slow down??
Thanks
