[February : National Speedbump Awareness Month]
Well, dang. After waiting what seemed like 142 years, I finally got the
Azteck 5.0 update. "Hot Damn!" sez I. Know I can do all those nifty things
that Lettuce claimes they can do. Also with all of this optimization stuff
that oughtta really speed up my software. . .
So I timed a set of 3-D and planetary calculations for the 3.6
compiled version, 31 seconds. Okay, not bad.
Then I install 5.0 (a real breeze BTW), recompile after making a few tweaks
to the code, and rerun the thing. 38 seconds. What the . . .??? Methinks
something be wrong here. Tweak some more. Recompile. 38 seconds.
I twiddle with the cc options. 38 seconds.
twiddle frobnicate. . . . .
Twiddle, twiddle
twiddle
38 seconds!!
Recompiled my touched up code under 3.6. 31 seconds. The problem is
A: I am totally braindead.
B: Maybe 5.0 is soooo fast the longer time is due to simple
Einsteinian relativistic effects.
C: I never learned how to tell time.
D: 5.0 is braindead and I should ask for a refund.
My compiler options are : -ff -so -wa -wr -wu -pb -wn
What gives?
