Experiments on connection concentrator

Experiments were done basing a DVD store application to verify the impact of connection concentrator.MAX_CONNECTIONS was set to 10,000 and MAX_AGENTS was set to 500.

Connections were scaled up each time in units of 2ooo.Throughput on the data server increased gradually as the number of connections increased.One other observation is related to memory consumed.With 2000 connections,the memory utilised was around 300 MB and it reached 1.5GB with 10,000 connections which is way less than the memory that might have been allocated with one-to-one association(Connection concentrator disabled).
