Hmmm I ran the standard version again, this time it took 3m 38s.
But it used 1 847 226 368 bytes. So only a small improvement in
render time, but a significant reduction in memory.
(I am not sure why I got the longer render time for the standard
version, some stuff might have been running in the background?)
I ran the test version again and it is about 1 490 000 000 bytes.
I will write a better test scene and post it as soon as I can.
Best wishes, /A
