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。 WebFio spawns a number of threads or processes doing a particular type of I/O action as specified by the user. fio takes a number of global parameters, each inherited by the thread unless otherwise parameters given to them overriding that setting is given. The typical use of fio is to write a job file matching the I/O load one wants to simulate.
