Data compressibility is only affected by the data pattern. Randrepeat and norandommap will only affect the randomness of the io for random workloads. For file_service_type, I think this is only used if fio has multiple files open at the same time, e.g. if multiple filenames are specified or nrfiles is used. -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
