How about some benchmarks?

A few years ago, I ran a benchmark on every computer I could find.
I used a variety of text-book examples, each chosen to find out
something specific about the machines.  Here are some of the numbers.

	Chip		Machine		Run Time (Seconds)
	-----		-------		----
	 8088		IBM-PC		 343
	 8086		ATT 6300	 242
	68000		Mac +		 200
	68000		Mac SE		 189
	80286		AST286		  55
	80386		ATT 6386	  42
	68020		Mac II		  42

Although I have not mentioned processor speed, each was state of the art
at that time.

Take a close look at the Mac + and Mac SE numbers.  About a 6% difference
overall.  I also looked at individual numbers for each of the ten parts
of my benchmark.  It looks like this:

	Component Tested	% Mac SE Is Faster Than Mac +
	----------------	-----------------------------
	Integer Math		  0%
	Floating Point		Less Than 1%
	Sorting			  7%
	Disk & I/O		 15%
	Recursive Procedures	~25%

(PS-please insert some type of standard benchmark disclaimer here.)

As far as I know, the 68000 in the Mac SE runs at exactly the same speed
as the 68000 in the Mac Plus--7.133MHz.  The integer math number above
would seem to support this claim.  The differences in the SE are more
modern ROM routines and improved I/O.  The I/O speed was just enough
faster to allow 2:1 interleave rather than the 3:1 suggested for the 
Mac Plus, which speeds up the fixed disk access a bit. 

> I ,myself, am almost completely content with my Plus.

Same here, once I got rid of that stupid hi-rise keyboard.  I still need
to have a unix machine around though (to unpack the news 8-).
