1、I/Os are scheduled directly from the database agents and as a result are not constrained by NUM_IOSERVERS.───从数据库代理程序直接调度非预取 I/O,因此非预取 I/O 不受 NUM_IOSERVERS 约束。
2、Often it is the first user to invoke a transaction that incurs the cost of I Os for reading in the indexes and data pages.───通常,第一个调用事务的用户将承受读取索引和数据页的成本。
3、SSDs shine really bright when random I/Os are being executed.───在执行随机 I/O Cao作时,SSD 的确更胜一筹。
4、Other graphs can be selected to show the total number of I/Os performed per second which will also indicate the improvement from SSDs.───可以选择其他曲线图来显示每秒执行的 I/O 总量,这也能体现通过 SSD 实现的改进。
1、A successful clustering strategy can reduce the number of DB2 GETPAGEs (and also I/Os), especially if many sequential scans use the clustering index.
2、No more than this number of I/Os for prefetching and utilities can be in progress for a database at any time.
3、Best performance is obtained using fast disks with write caching; i.e. those that can cache I/Os to memory in the disk subsystem and guarantee that they will be written to the disk media eventually.
