Xpath vs DOM vs BeautifulSoup vs lxml vs other Which is the fastest approach to parse a webpage?

I know how to parse a page using Python. My question is which is the fastest method of all parsing techniques, how fast is it from others?

The parsing techniques I know are Xpath, DOM, BeautifulSoup, and using the find method of Python.

lxml was written on C. And if you use x86 it is best chose. If we speak about techniques there is no big difference between Xpath and DOM - it's very quickly methods. But if you will use find or findAll in BeautifulSoup it will be slow than other. BeautifulSoup was written on Python. This lib needs a lot of memory for parse any data and, of course, it use standard search methods from python libs.
