Tuning Performance

Tune deployments in the following steps:

Consider the issues that impact the performance of a deployment. See "Defining Performance Requirements and Constraints".
Tune and test the downstream servers and applications:
- Tune the downstream web container and JVM to achieve performance targets.
- Test downstream servers and applications in a pre-production environment, under the expected load, and with common use cases.
- Make sure that the configuration of the downstream web container can form the basis for IG and its container.
Tune IG and its web container:
- Optimize IG performance, throughput, and response times. See "Tuning IG".
- Configure IG connections to downstream services and protected applications. See "Tuning the ClientHandler/ReverseProxyHandler".
- Configure connections in the IG web container. See "Tuning IG's Tomcat Container".
- Configure the IG JVM to support the required throughput. See "Tuning IG's JVM".
Increase hardware resources as required, and then re-tune the deployment.

The following figure shows an example configuration for IG, its container, and the container for the protected app:
