"My testing shows that using hardware costing about
$1.000 to run Liferay 5, I am able to serve between 300 to 2200
requests per second. This test scenario mimics hosting a web site
consisting of several thousand pages, with at least 1.000 users
simultaneously browsing the site. Note that this does not take the
bandwidth to the Internet into consideration, since I have tested
on a Gigabit LAN."
