To optimize testing with WebDriver over Selenium RC, utilize browser-specific drivers, implement the Page Object Model, use implicit and explicit waits, choose efficient locators, run tests in parallel, minimize browser interactions, and consider headless browsers for faster execution. This enhances performance and maintains code clarity.
