Configure the network
The following recommendation about the test infrastructure is necessary to increase the performance of the heavy load testing.
Distribute NeoLoad communication channels over different networks
During the test phase, NeoLoad conveys three distinct types of information:
- Scenarios are dispatched from the Controller to the Cloud Load Generators (scenario distribution).
- Scenarios are actually played to the application server (load generation).
- Monitoring information is sent back to the Controller.
Separating those three information channels on distinct networks achieves the most efficient network setup.
To obtain a good trade-off between infrastructure costs and efficiency, it is advised to use remote Monitoring Agents in the application server sub-network. Particular attention must be paid to the firewall, if any, between the Cloud Load Generators and the application server.
It may prove necessary to configure remote Monitoring Agents that are hidden be a firewall (polling mode). See Use a firewall.
