It does both... the parameter _IOPROCS_SWITCH handles the "number" of I/Os after the second/n'th thread gets the work to write to the harddisk. So if there's low I/O it's indeed serialized, if one thread is too busy or the number of concurrent I/Os is higher than _IOPROCS_SWITCH && _IOPROCS_PER_DEV is > 1 then it's executed in parallel.
