If I render a (Widescreen[1]-)Image ...
... with a resolution of 3840x1024 ...
... and this image renders at a rate of 1PPS (dooh ... it increased in the
    last line, it startet the hard part[3] with 26PPM)
... and I still have 500 lines to do ...

... this will take a loooong[2] time ?

I think about halting the pic and continuing with more conservative[4] AA- 
settings ...


[1] I'm rendering a wallpaper, that fits in my multimon-environment[5]
[2] just a short calculation: 3840 Px/line means ~1 line/h ...
    ... meaning >~500h ... meaning .... oh my god ...
[3] a ground-plane with (fresnel)reflection blur, a crackle(metric 1)- 
pigment wich is reflecting a quite complex TTF with fade-color.
[4] +AM2 +AA0.3 +R4
[5] (3x 1280x1024)
[6] /me likes to write footnotes ...
[-1] Error: footnote overflow

I would confirm that you must have done either:
...something weird in your scene which takes forever to render[1]
...something wrong in your scene which could be made better[2]

But that's hard to say with no source-code...

[1] too many merge's where union is sufficient, stacked-planes, area_lights?
[2] too large container objects for isos or medias?

Yes
> ...something wrong in your scene which could be made better[2]
Probably

> But that's hard to say with no source-code...
will follow when image is ready ...

no merge, only csg is one union of 80000 rounded-cubes(which of course are  
again unions). I presume that the automatic bonding worked quite well, as
this object is already done computing

> [2] too large container objects for isos or medias?
no isos, no media, for bounding look at answer_of([1]).

the time-consuming part is the ground-plane, which uses fresnel- 
reflection-blur[23] ...

above this plane there is a TTF-Object, scaled z*200 (away from Cam) and  
"filled" with fade-color ... so all intersections of the font have to be  
computed ...
furtermore there are also 2 ground-fogs defined ...


but what the heck ... raytracing is no fun, unless pps < 5 (hey...  
currently I have 100ppm)

[23] I only set 16 layers ...

Perhaps your computer's specification would solve the riddle, because
what you seem to have in your scene could be "worse"...

Well, I'm seeing forward to see the result!
