This year I've been focused on how we can use less while getting more out of less.
What is you see is a single core 1gb of memory system that is fully function and can accommodate thousands of simultaneous connections

Using SYSTEMD we managed to halve consumption of memory from on average 512 to on Average 156.

The spike you see was a moment in time where we chose new compoonents, made our migrations and after the migrations were made we were able to free up ram.
The additional ram was added because the first migration was unsuccessful and caused the system to become non-responsive.
