I would like to be able to spin up more than one fio instance running on the same platform concurrently. For example, I would like to run one fio instance in time_based mode doing some stuff. And after a fixed period of time then start a non-time based fio instance doing some other stuff. I have tried it out and to my untrained eyes it looks like its going OK. But I'd love to hear from others with more experience in this area. Is this something that is recommended? Will my data skew in some way because fio expects there to be only one instance of itself playing at any one time? Any advice would be much appreciated!
