I run a website with 10k unique pages. If I leave the gates open, Meta hits it 200.000 times per day. Every day. What are you paying developers $500k for Mark?

200k req/day = 2.3 req/s

That's bad for static content.

Try adding search, with pagination and 16 filters that can toggled on off. And 1000 tags, give each page 5.
