Description (*)

The cache named compiled_config hosts all the di.xml compilation outcomes, including information about plugins, virtual classes etc.

With Magento 2.4.8 upgrade, the performance degradation of tests execution for multiple projects became significant. Mostly, due to the CPU usage.

Turning on compiled_config mitigates the issue, slightly improving the overall Integration Tests performance, without affecting areas such as Configured Object Manager.
