Comparison between underlying MacOS versions

You can run Mac OS 9 and Mac OS X on PowerMac, and you can available Classic environment (Mac OS 9 emulation) on Mac OS X also. It must have great significance to check if there are some performance difference between these underlying OSes or not. Here, compare following reports measured on an identical Macintosh PowerBook G3 hardware:

reportId	date	R	Pltfm	Clr	VW	Jun	All	crt	shw	ben	txr	trn	vor	del
BF83CF08	2002Oct26	4	mac	24	7	454	13.8	7.3	1.3	4.9	11.0	17.5	26.5	28.4
BF83E56F	2002Oct26	4	mac	24	7	454	14.9	7.5	2.6	5.3	12.0	18.3	28.3	30.6
BF83F5C1	2002Oct26	4	unix	24	7	454	-	-	-	-	-	12.2	24.8	26.1

Note:

reportId: BF83CF08 on pure Mac OS 9.2.2
reportId: BF83E56F on Mac OS X 10.2.1 [Classic: Mac OS 9.2.2 emulation]: Naturally, a little slower than the pure MacOS 9 result above.
reportId: BF83F5C1 on pure Mac OS X 10.2.1: A little faster than the classic environment's result above.

Please refer to Legend of result summary list for the meaning of each column in the heading (abbreviated as crt, shw, etc.).
