Thanks for the clear explanation.
When the G3 server was first announced, Apple promoted them as much more responsive for file serving than the older 604e machines. I doubt, however, that an early G3 had much to commend it above a 604ev in a server. The greater advantage might have been the G3's bus speed, as it would presumably speed up I/O etc.
A 604ev is a rather different as well as a faster processor than a 604e (even more the 604), and the 1MB inline L2 cache in the 8600/ 9600 "Kansas" architecture is much superior to the 512k cache on the 9500's logic board. The last of the 8600 and 9600 machines were very capable for their time, though the bus speed was indeed 50MHz max.
