Why do processes with higher priority to be allocated more timeslice?

Initially, I think that the scheduler should enlarge the timeslices of
CPU-bound processes to improve throughput. But, now I have realized
that the two goals of schedulers, namely shorter latency and higher
throughput, can not be achieved at the same time. Linux scheduler may
prefer to the former. Thanks! :-)
