13 | help | |
14 | This option causes statistical information to be gathered on local | |
15 | caching and exported through file: | |

19 | The gathering of statistics adds a certain amount of overhead to | |
20 | execution as there are a quite a few stats gathered, and on a | |
21 | multi-CPU system these may be on cachelines that keep bouncing | |
22 | between CPUs. On the other hand, the stats are very useful for | |
23 | debugging purposes. Saying 'Y' here is recommended. |
