Not sure what brutish computer you have at your disposal, but even
without AA I don't see render times anywhere close to 1s here. More like
a bit under 4 minutes with POV-Ray 3.6.

For some reason, POV-Ray 3.7 seems to grind to a halt -- possibly
because its handling of max_trace_level with regards to fully
transparent surfaces is different.
