> How can that be possible? The DNS lookup takes longer than that and you still haven't even gotten to your site.
Me too. But if you ever did marketing landing pages for products you might know that one landing page is not enough. You need thousands which match to Ad Word campaigns or which are optimized to different SEO fields, domains and whatever. While you still could manage this with Next and nice components, Next's subpar routing might be an obstacle.
More relevant metrics are TTFB (time to first byte) and TTI (time to interactive).
I wouldn't want to implement a marketing site in express/pug. I want the flexibility of components and all the other benefits that React offers.
