Any rule of thumb for using switch vs if-else for performance reasons? Basically like let's say if you need to use switch case if there are more than 4 conditions?

It seems that the compiler is better in optimizing a switch-statement than an if-statement. Check this out: http://www.blackwasp.co.uk/SpeedTestIfElseSwitch.aspx

Switch Case has better efficiency and is faster and it uses a jump table method to reach the required block to execute. If-else uses different technique! In "if" statement, we can easily provide a range condition (for example: age>=18 && age<=45). There is no such option when using switch case: We can only provide a particular value while using switch case. Both have their own importance in different types of programs.
