Try 5: a few hundred users, interacting properly

It turns out that in the hyperactivity agents were not interacting in Ejabberd resource tests/try 4.

For this test several hyperactivity instances were used, each running 50 clients. 4 XO laptops were also connected, so the total number of clients was at most stages 50n + 4.

Memory use

Here you can see the memory use is slightly over 1 MB per user, and growth is perhaps slightly more than linear.

Memory use vs connections

This shows max-median-min values for stable points along the way.
