aka the 768kbyte IBM cambridge science center CP/67 360/67 with 104
pageable pages (after fixed memory requirements) had better response and
aggregate throughput with 85 users (and "global LRU") than the 1mbyte
IBM grenoble science center CP/67 360/67 with 156 pageable pages (after
fixed memory requirements, i.e. 50% more pageable pages for users than
cambridge machine) with 35 users and "local LRU" page replacement and
"working set dispatcher" ... as described in academic literature.

so it was effectively same hardware and nearly same system ... except
for the "global LRU" page replacement vis-a-vis "local LRU" page
replacement ... which supported the work done for Stanford Phd work more
than decade later on "global LRU'.
