Is it just me, or does terminology like
"55% faster" seem ambiguous or at least just plain funny?
We all know what it means, but it just sounds bad.
I'd rather just see people (Apple) say it runs as 1.55 times the speed.
This sounds to me like it could be interpreted as:
NEWSPEED = BASESPEED * 1.55 <<- what it must mean, I assume
(NEWSPEED - BASESPEED)/BASESPEED = .55
=> NEW = .55 BASE + BASE = 1.55 * BASE
(hey! consistent!)
(NEWSPEED - BASESPEED)/NEWSPEED = .55
=> NEW = .55 NEW + BASE => NEW = 2.22 BASE
<<- I wish, dream on
BASESPEED/NEWSPEED = 0.55 => NEWSPEED = 1.18 * BASESPEED
or even, 55% of the machine is (somewhat) faster, the rast is the
same, hence the total speedup is
(UTILIZATION OF THIS 45 % ) * 1.0 +
(UTULIZATION OF THIS 55 % ) * UNKNOWN_SPEEDUP_FACTOR

You really ought to have a disclaimer if you say things like this without support from your university ,-) Seriously speeking, my mac and my HP calculator seem to agree on on: NEWSPEED / BASESPEED == .55 => BASESPEED ~= 1.82 * NEWSPEED Maybe I should get a IIci instead of the SE/30. It might give better results. ,-) (If you didn't get it...) Really, the only thing I can think of, that "55 % faster" might mean, is that the computer does 155 % more per time unit. All else, really, isn't very logical. Follow-ups to alt.religion.computers. h+@nada.kth.se == h+@proxxi.se -- You are being watched.
