The January 1987 (vol 38 #1) issue of the H-P Journal contains an
article on the HP3000 series 70 cache, which goes into great detail on
how they instrumented the older models to determine what cache
parameters to change in the new model.   One quote from the article,
and a reference:

"...it has been shown that operating systems have rather poor locality
compared to user programs."  They don't give a derivation for this finding.

The reference:
A. J. Smith, "Cache Evaluation and the Impact of Workload Choice",
Reprot UCB/CSD85/229, March 1985, Proceedings of the 12th International
Symposium on Computer Architectures, June 1985, pp 64-75.

To subscribe to the HP Journal, send your request to:  HP Journal, 3200
Hillview Ave, Palo Alto CA  94304 USA.  "Allow 60 days."  They'd probably
just send this issue if you asked.  The journal seems to have an assortment of
technical articles on their computers (especially the RISC machines), software,
and instruments, each about 1/3.  It's free and I find it worth reading.
