n++ uses unary operator while n+1 uses binary operator thats why it takes less instruction in n++ rather than n+1, that's why n++ is faster.

n++ takes more than one instruction, ++n is faster. n++ has to store n, increment the variable and return n, while ++n increment n and return without storing the previous value of n.

If n++ executes faster than n = n + 1, the reason for it is simple: your compiler has a poor optimizer.
