I have included both libgpiod and lgpio libraries in the process.
I understand that the control period varies because of the infinite loop. However, lgpio resulted in more variation.
Why is there such a difference between lgpio and libgpiod? Both are doing the same process, also in C.

Result of libgpiod is below.

And, lgpio is below.
