org.apache.sis.util.logging.PerformanceLevel defines some levels for potentially lengthy data processing such as loading data. The current levels are listed below. Two of them are problematic:
- PERFORMANCE: this name does not said what we mean here (any potentially lengthy task).
- SLOW: ok
- SLOWER: ok
- SLOWEST: suggests that nothing can be slower, which is not true.
I suggest to remove completely the SLOWEST level. A need for 3 slow levels has not been demonstrated anyway, so we would reduce to 2.
The PERFORMANCE level could be renamed PROCESS or TASK. We are looking for a word meaning "potentially lengthy task". Alternatively we can just remove it and use Level.FINE instead.
