| Avoiding the flush operation at the end of each append results |
| in a performance gain of 10 to 20 percent. However, there is safety |
| trade-off involved in skipping flushing. Indeed, when flushing is |
| skipped, then it is likely that the last few log events will not |
| be recorded on disk when the application exits. This is a high |
| price to pay even for a 20% performance gain. |
