As an aside to this, do 2.6 kernels make some efforts to keep a process on a
specific core anyways recognising the benefits to the cache of doing so (I
suspect they do but maybe I just dreamed it up)?
yes - the code is pretty reasonable, though probably more tuned towards
typical desktop/webhost-type applications. there are affinity heuristics for
managing which core a proc will be run on, as well as for guiding memory
allocation on numa machines. (pretty soon, of course, all multi-socket
machines will be numa and need these issues handled...)
