Wrong time measure in some implementations

[vikman90]

These implementations are yielding an unusually inefficient result:

• C++
• Go
• Rust

This is the performance table, supposedly measured in ops/ms:

Implementation	Step perf (max)	Step perf (avg)	Disc. perf (max)	Disc. perf (avg)
JavaScript	43.000,00	24.331,97	2.567.812,50	716.081,97
C#	62.594,50	42.403,85	3.908.416,67	709.109,47
PHP	34.500,00	5.113,62	607.800,00	212.727,68
Java	38.000,00	4.605,37	825.000,00	192.100,51
Python	38.000,00	4.605,37	825.000,00	192.100,51
C++	887,50	240,02	28.859,81	2.450,07
Go	514,29	106,26	20.288,46	1.801,85
Rust	597,22	126,77	24.791,63	1.652,69
