CPU benchmark

I wrote a simple Python program, which builds R-Tree index for 100k nodes.

The program runs single thread and this means that only a single core of a CPU is working.

3m 31.322s Intel(R) Core(TM)2 Duo CPU T7300 @ 2.00GHz
3m 2.835s Quad-Core AMD Opteron(tm) Processor 2372 HE @ 2.1Ghz
1m 31.393s Intel(R) Core(TM) i7 CPU 975 @ 3.33GHz
