    So 25QPS crashed the site? What is it running on, a Raspberry Pi? This isn't rocket science. We handle ~1000 seat reservations per second for @euskalencounter on two servers with Python/Flask/PostgreSQL. How do people make things perform so poorly? https://www.theguardian.com/politics/2019/mar/21/petitions-site-crashes-after-thousands-back-call-to-revoke-article-50?CMP=fb_gu …pic.twitter.com/Px5e8yiY90

        Think about it, we can *encode 4K video* in real time on a modern server easily. That's 30 or 60 multi-megapixel images per second going through complex algorithms. Recording that someone clicked a button is trivial in comparison. How do people get this so wrong?

        And for a petition site you can just dump records in a DB, and cache queries and counts. For reservations we actually need a hard cutoff when seats are exhausted and that introduces a bottleneck hotspot. A petition site is embarrassingly parallelizable.

        Even a Pi could handle that comfortably, really.

        As bad as that is, it doesn't sound unsurprising for the civil service, or a contractee.

        Poor database schema design, probably.

        True, caching / architecture is way more important than choice of technology
