[Server-devel] more ejabberd testing

[Douglas Bagnall]

The bad news is the last lot of testing I did is very untrustworthy,
due to the shared roster not working[1].

The good news is I've repeated the tests, with the shared roster.  Not
so good, is the results aren't so good.

Counting only times with a stable number of clients,
memory use looks like this:

On that wiki page, there is also a photo of a few laptops showing
their neighbourhood views: each has quite a different idea of its
surroundings.

not recreate the @online@ group.
