// +W320 +H240

camera { location <0,50000,-100000> look_at <0,-10000,0> }
light_source { <-700000,1000000,-400000>, rgb <1,1,1> }
plane { y,0 pigment { color <0,.8,0> } }

#declare R = seed(0);
#declare Count=0;
#while (Count < 5000)

sphere {
        <0,1000,0>,
        1360  // 1350 works fast
        pigment { color <0,.5,0> }
        translate <(rand(R)-.5)*500000,0,(rand(R)-.5)*500000>
        }

#declare Count=Count+1;
#end


This takes over 4 minutes if the radius is 1360. If I change it to 1350 then
Render Time is just 1 or 2 seconds.

Tested with Athlon64 3200+, 3.7.0.beta.40 (Windows XP 32-bit) and 3.6.1 (Ubuntu
10.10 64-bit).
