Our results (see Table 1-2) show a linear scaling as we increasedthe number of machines. Overall, we demonstrated that Sametime could support300K concurrent Sametime Links clients, with a high probability that more can besupported with additional machines.Table 1-2 Scaling Sametime LinksCommunity hub machinesSTLinks/MuxmachinesSametime Links clientsupported1 1 25,0001 2 50,0001 3 75,0001 4 100,0002 8 200,0003 12 300,000Prior to the release of Sametime 3.1, customers and the development teamexperienced many issues getting to this level of scalability.
