0 votes 0 votes usually it depends on what kind of requests are presents in queue. but in std books like tanenbaum says sstf is provide better throughtput in respect of waiting time than elevator algorithm.(general approach) bcoz in elevator algorithm if request is come behind the head it service that request only in round trip.(huge wait) even one question also ask in gate about it.(remember sstf and c-look algorithms are used as default case) hope its helpful. https://gateoverflow.in/1463/gate1999-1-10 Aks9639 answered Feb 8, 2019 Aks9639 comment Share Follow See all 0 reply Please log in or register to add a comment.
