Hi, all Fio will exactly access each block once by default. But it is not the case we want to use cache tier. The reason we use it is lots of content will be access repeatedly so that there is lots of cache hits. I find random_distribution can alter the acess distribution, but hard to exactly set the hit : miss rate for the test. Is there any way to do this?
