Running valgrind today paid off, I think - one significant (i.e.
memory-corrupting) bug and one memory leak (0.4MB leaked in a
relatively short run) found & fixed :-)
Wow. Very nice job. Was that what you commited?
Thanks :-)
Yes, that's changesets eb0f02742864 and

> Well, thank you for the effort, but I'm not sure these virtualized
timings say much. They won't correspond to running the game on a
machine's 'real' OS... the virtualization software influences the
measurements.
Very well. I'll run it on my Linux computer (non virtualized) and a
gaming system I should point out..................
Of course it is - these days I use it for playing the profiling game :)
(Oh, and that nifty 'Valgrind' game. It even has a boss key.)
Here you go: http://dl.sv.nongnu.org/releases/glob2/profiling.tar.bz2
Those are the new results. Much different. Perlin and clouds seem to
dominate?
Yes, this is interesting!
I haven't used the '-h' switch myself until now.
The busy callpath is
Game::drawAll -> Dyn.Clouds::compute -> PerlinNoise::Noise ->
PerlinNoise::Noise3d
Is there any chance that the noise can be computed using integers, or
cached?
It seems it's all multiplying and adding, so I'm guessing it might.
A visualization of the results are available here:
