Here you can see:
- `ExpressionTransform` was executing `sleep(1)` function, so it `work` will takes 1e6, and so `elapsed_us` > 1e6.
- `SourceFromSingleChunk` need to wait, because `ExpressionTransform` does not accept any data during execution of `sleep(1)`, so it will be in `PortFull` state for 1e6 us, and so `port_full_elapsed_us` > 1e6.
- `LimitsCheckingTransform`/`NullSource`/`LazyOutputFormat` need to wait until `ExpressionTransform` will execute `sleep(1)` to process the result, so `need_data_elapsed_us` > 1e6.
- `SourceFromSingleChunk` need to wait, because `ExpressionTransform` does not accept any data during execution of `sleep(1)`, so it will be in `PortFull` state for 1e6 us, and so `output_wait_elapsed_us` > 1e6.
- `LimitsCheckingTransform`/`NullSource`/`LazyOutputFormat` need to wait until `ExpressionTransform` will execute `sleep(1)` to process the result, so `input_wait_elapsed_us` > 1e6.
