Iops fio
Web定义fio如何下发IO请求,通常有同步IO和异步IO:同步IO一次只能发出一个IO请求, 等待内核完成后才返回。 这样对于单个线程IO队列深度总是小于1,但是可以透过多个线程并发执行来解决。 WebFrom the preceding sequential test results, the bw (bandwidth), IOPS values are pretty high when compared with random test results. That is, in sequential test cases, we gain approximately 50% more IOPS ( read=243, read=242) than with the random IOPS ( read=127, write=126 ). Fio also provides more information such, as I/O submission …
