They are usually slower but they can still be pretty fast. Also, with integration tests, you can choose the granularity of your test. You don't need to test end-to-end (of course this is the slowest), you can just test a single module with all its dependencies. If you don't mock out dependencies, then it's still technically called an integration test.
