Investigate Potential Delays in Slot Ticker

[olegshmuelov]

We are observing occasional delays (exceeding 100ms) in the logging of ticker events within our SlotTicker. This might be linked to the processing logic in handlers. The delay could be due to blocking operations, shared resource contention, or other bottlenecks within the event handling loop.

We need to add timing logs to key operations in these handlers and ensure that the SlotTicker is not being impacted by concurrent access or slow operations.
