Playwright's getByRole is 1.5x slower than CSS selectors

I recently wrote a blog post where I take a deep look into Playwright’s locators, specifically comparing the Page#getByRole locator with CSS selectors in terms of performance.

Playwright’s getByRole is 1.5x slower than CSS selectors because Page#getByRole uses querySelectorAll('*') and matches elements by the accessible name.

The post breaks down how `getByRole` works under the hood, how it stacks up against CSS selectors performance-wise, and what this means for your testing suites.

Would love to hear your thoughts!
