This graph shows the number of new TCP/IP connections (y-axis) opened and the number of connections that are shut down for each second of the load test scenario (x-axis).
Elapsed time since the start of the run.
TCP/IP connections per second.
New connections versus hits per second:
The number of new connections should be a small fraction of the number of hits per second, because new TCP/IP connections are very expensive in terms of server, router and network resource consumption. Ideally, many HTTP requests should use the same connection, instead of opening a new connection for each request.
