Performance tuning for locations

Tune the PoP controller parameters to support high-workload Synthetic test environments and improve throughput for tests with user credentials.

To support workloads above 2000 Synthetic tests per minute, tune the PoP controller as follows:

• To support more tests with user credentials, tune the controller.scheduleTestMaxPoolSize parameter to a higher value. To support this parameter, upgrade to Synthetic PoP 1.1.2 or later.
• To support more results that are sent to the Instana backend, tune the controller.publishAARThreadPoolSize parameter to a higher value.

If you tune the parameters controller.resources.limits.cpu to 500 m, controller.resources.limits.memory to 500 Mi, controller.publishAARThreadPoolSize to 40, and controller.scheduleTestMaxPoolSize to 15, the PoP controller can support 9000 API Simple tests with user credentials per minute.
