Instruction cache behavior and branch prediction are used to improve the functionality of a computing device by profiling branching instructions in an instruction cache to identify likelihoods of proceeding to a plurality of targets from the branching instructions; identifying a hot path in the instruction cache based on the identified likelihoods; and rearranging the plurality of targets relative to one another and associated branching instructions so that a first branching instruction that has a higher likelihood of proceeding to a first hot target than to a first cold target and that previously flowed to the first cold target and jumped to the first hot target instead flows to the first hot target and jumps to the first cold target.

Correlating two storage rings based on an access rate for an object. A correlative dual hash ring includes a first ring of storage drives and a second ring of storage drives. Objects and replicas are allocated to either a first ring or a second ring.
