If your services are doing simple inquiries into a well-indexed database that take less than 100 milliseconds, then you will see a big difference between the two choices.
如果您的服务是对一个具有良好索引的数据库的简单查询，花费少于100毫秒的时间，那么您将看到这两个选择之间巨大的差异。

当一个文档进入系统时，它存储在文件服务器上并在DB 2数据库中编制索引。
If this were our theory, we might change our logging to log_update=2, which will record a time stamp for each view that is indexed, instead of at the database level.
如果这是我们的看法，我们可能将记录改为 log_update=2，这样将为建立索引的每个视图记录时间戳，而不是在数据库级别进行记录。
