Rob Thompson's Blog:
Switch vs. If
February 01, 2008 @ 14:28:00

Rob Thompson has posted about some simple benchmarking he did comparing the speed of a series of "if" statements versus one "switch" with multiple cases.

I got curious about which is actually more efficient at matching a random integer with a set of conditionals. So, I setup a script to create a set of large scripts to test the speed of these different constructs. Using the 'time' command, I measured the speed at which the condition could match a random number.

His results found that the switch statement is generally more than 2 times as fast at matching a simple integer. His tests, however, didn't go through much more than this simple test. It'd be interesting to see what it would do with something more complex (like longer strings or handling the result of an evaluation inside the definition of the switch().
