== 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 approximately linear or slightly in excess thereof.  The server has 1GB of ram.

=== Memory use vs connections ===

This shows max-median-min values for stable points along the way. (Where the readings appear to stack up on each other, the number of connections varies by one or so).

=== CPU usage ===

=== The laptops ===

Note that they all see a different number of clients.
