I am interested in cache design issues. How big a cache? How associative? What kind of hit rates? How big a line size? How much time is spent in reload? What is the total running time? Writeback policies? Most of these are general cache design issues but I am especially interested in whether the kernel acts significantly differently than the average program the user might write and what parameters might be changed to allow for differences. -- My left foot is digital, my right foot is analog.
