Comment (by strk):

 An STRtree node capacity of 256 resulted in raising the timings to ~5
 seconds.
 A node capacity of 32 made timings =~ 2 seconds.
 A node capacity of 4 made timings =~ 686 ms.
 A node capacity of 2 made timings =~ 532 ms.
 A node capacity of 1 resulted in a segfault.

 I'm not sure what to make of these numbers.
