What is the root use case you are trying to solve? What kind of solr install is this and do you not have control over the clients or what is the reason that users overload your servers?
Normally you would scale the cluster to handle normal expected load instead of trying to give users timeout exceptions. What kind of query times do you experience that are above 1s and are these not important enough to invest extra HW? Trying to understand the real reason behind your questions.
