[.15.5][Headless] Significant performance decrease headless

[Fixitt]

With the release of the last patch .15.5 (Linux Headless) our dedicated multiplayer is now showing extreme hard disk usage and connecting clients are never able to "catch up" and are disconnected.

Doesn't appear to be hardware related as system is significantly underutilized
Operating System: CentOS
Hardware: Standard DS1_v2 (1 Core, 3.5 GB memory)
Disk: Premium SSD - 30 Gigabyte
IOPS Limit: 500
Throughput Limit: (MB/S) 100
CPU Average: 4.93%
CPU Max: 33.49

Details:
Prior to patch system was running at an average of 4.93% CPU, 125.68 KB/s read, 181 KB/s write with periodic spikes during save activity of DISK WRITE 3.82MB/s. After Patch hard disk activity is extremely inconsistent and i am receiving hard-disk write spikes in excessive of 36.07 MB/s read and 7.85 MB/s write.

So i realize I am basically talking to myself in this bug report haha, but i have found the issue.

I had a few thousands construction robots performing a long-standing deconstruction request. The moment i ran out of Logistics Storage Chests for the robots to place the items into, OR if i canceled the deconstruction request entirely the performance issues completely disappeared. I will leave this post up for future reference when a developer has a chance to get to it.
