Green Cloud Computing is a very interesting area that deals with different ways to reduce the energy consumption of clouds and data centres. Software solutions (native applications or those running inside containers) whose optimization (especially at the binary code level) can achieve a significant increase in computational performance or a reduction in computational time and thus directly reduce power consumption have a significant impact on the power consumption in these environments. In our study, we focused on the optimization of programming code in the C++ programming language, both in terms of the syntactic constructs of the programming language and the code generator itself. Our findings show that the difference in the efficiency of the resulting binary form of the program can be as much as tens of percent lower in terms of energy consumption.
