The CFQ works well for many general use cases but lacks latency guarantees. The deadline excels at latency-sensitive use cases ( like databases ), and noop is closer to no schedule at all. On the other hand, MongoDB schema design takes a document-oriented approach. Two other schedulers are deadline and noop.

This isn’t true (more on that in a follow-up post), and sites which are built this way implicitly require more script in each document (e.g., The server sends it as a stream of bytes and when the browser encounters each of the sub-resources referenced in the document, it requests them. for router components).

Unless a site is installed to the home screen as a PWA , any single page is just another in a series of documents that users experience as a river of links.

You should expect one-time implementation cost (depending CMS and business requirements it can cost 200,000 USD to 3M USD) and yearly hosting infrastructure cost (proportional to load and traffic but typically 30,000 USD - 300,000 USD per year). Most of cloud object/blob storage services have native support for static site hosting.
