WPML and Supercache works together?

On the Basic area we can test the cache but in only shows .com version

Does super cache also works for the 2nd language? com/en/ I can see on the right side of the panel, some of the articles in the 2nd language .com/en/xxx are cached however when we test the home page .com/en/ for the second language the page load time actually doubles.

Thank you
