Switch Vs If Else Performance. Better performance in many cases a switch statement will perform better than an if else chain. A switch statement tests expressions based only on a single integer enumerated value or string object.
The first int tested is 0 which gives it priority over other tests. The primary difference in performance between the two is that the incremental cost of an additional condition is larger for if else than it is for switch. I have tested switch s performance every single situation 100 000 000 times against the following if else if trees.
So is switch in this case faster.
The strict structure makes it easy for an optimizer to reduce the number of comparisons that are made. If else better for boolean values. An if else statement can test expression based on range of values or conditions. If else conditional branches are great for variable conditions that results into boolean.
