This option has meaning only when delayed_commits is set to On. it governs when a COMMIT entry in the transaction log is written to disk. With delayed_commits set to On, the database server waits for the number of milliseconds set in the delayed_commit_timeout option for other connections to fill a page of the log before writing the current page contents to disk. See delayed_commits option [database].
