Optimize core for large datasets

**Description**
Currently utils lacks proper monitoring support.

**Proposed solution**
Add configurable monitoring with sensible defaults.

**Priority**: Low/Medium

Start by locating the utils area and any existing monitoring or telemetry entry points; the issue does not name specific files or tests. Clarify whether the goal is monitoring for large datasets, then define the configurable settings, sensible defaults, and tests that demonstrate monitoring works before considering the issue done.
