Here is result of extended test made after Warp's suggestions:

Total CPU time used was measured in seconds.
The same machine, script and calculation was used.
Every scene was started 3 times. result was averaged.
Two loops as earlier but with max. 1000 so, it was 1.000.000 use of calculation:

external macro       - 1026,47 [s]
internal macro       -  350,73 [s]
calculation on-place -  221,15 [s]
external function    -  179,62 [s]
internal function    -  178,68 [s]
