JavaScript Performance Hit Calling Function vs. Inline

I know there is a performance hit when calling a function vs just running the code right there but I was curious how much that would be in different browsers. I went over to one of my favorite JS testing sites, http://jsperf.com/ , and setup a simple test. Running a few tests on a few different browsers suggests that there is about a 50% performance hit when calling a function with a small task.
