Results / raw data and graphs

This section provides the raw data results of each test, with accompanying CPU usage graphs. The graphs show that there is a ramp-up period while the users are being logged in. After the ramp up period, the CPU usage pattern changes.

Test I

25,000 users, one community hub server, one Sametime Links/MUX server
