Have any studies been done on how the kernel's locality of reference
compares to that of a typical application such as the compiler or
nroff? 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.
