Reiser4, Part II: Designing Trees that Cache Well
In upcoming articles we will discuss why, even when nothing is cached in memory, Reiser4's performance is much higher than that of ReiserFS v3, why dancing trees are better than space-usage balanced trees and how we added support for transactions while at the same time greatly reducing the amount of data that is written twice.
Hans Reiser (firstname.lastname@example.org) entered UC Berkeley in 1979 after completing the eighth grade and majored in “Systematizing”, an individual major based on the study of how theoretical models are developed. His senior thesis discussed how the philosophy of the hard sciences differs from that of computer science, with the development of a naming system as a case study. He is still implementing that naming system, of which Reiser4 is the storage layer.
