Try 6: Shared roster with new TLS code

This is much the same test as Ejabberd resource tests/try 4, but without manual interactivity testing and a slightly longer gap between jumps in the number of clients.

Memory use

Here you can see the memory use is slightly over 1 MB per user, and growth is approximately linear or slightly in excess thereof. The server has 1GB of ram.

Memory use vs connections

This shows max-median-min values at stable numbers of clients (min. 3 minutes).

These are the numbers being graphed:

resident_mem
 clients              minimum     median    maximum

Virtual memory

The virtual memory size shows a smooth increase:

CPU usage

Cumulative CPU use by the ejabberd process:

Load averages, by connections and by time:
