Why Go/Golang

Understanding Why Go/Golang

Hardware limitations:

Moore’s law is failing –

-The number of transistors on a microchip doubles every two years, though the cost of computers is halved.

-Growth of microprocessors is exponential.

Single-thread performance and the frequency of the processor remained steady for almost a decade

If you are thinking that adding more transistors is the solution, then that is wrong.

This is because at a smaller scale, some quantum properties start to emerge (like tunneling) and because it costs more to put more transistors

Thoughts –

-Manufacturers started adding more and more cores to the processor.

-Introduced hyper-threading

-Added more cache to the processor to increase the performance

Its limitations –

-Adding more cores to the processor has its cost too.

-We cannot add more and more cache to the processor to increase performance as cache have physical limits: the bigger the cache, the slower it gets.

If can’t rely on the hardware improvements, the only option is to write more efficient software to increase the performance
