How to detect:
Multiple Trino configuration parameters set to non-default values, with some configured lower than defaults, causing performance degradation.
Recommended action:
Remove custom configuration settings and revert to Trino defaults. Specifically review task.max-worker-threads and task.concurrency which are set to 8, potentially lower than optimal for the hardware.
