Aren't web-frontends just basically HTTPS / AES-GCM cores that shuffles data between RAM and PCIe / Networking? I'm thinking like Cloudflare or Twitter. There's not much compute going on at this level (all the compute would be at the SQL-server or Application-servers or other backend equipment handles). What's needed for frongend / proxy code is AES for handling the HTTPS / TLS connection, and lots of threads to handle all the different connections.
