System Load Time & Plain HTML StandardsThis document outlines the performance benchmarks, baseline network expectations, and structural compliance tests for documents hosted on bbsys.net. We enforce strict payload caps to guarantee sub-second rendering across all network interfaces.
Performance Baseline & Targets:
- Initial Packet Budget: The HTML file itself should stay under 14.6 KB so it can arrive within the initial TCP congestion window (about ten packets). Images such as the logo are separate requests.
- Time to First Paint (TTFP): No render-blocking requests, so a page can paint as soon as its HTML arrives. After that, network latency rather than page weight sets the floor.
- Zero External Requests: Pages must render fully without blocking on third-party fonts, external stylesheets, or analytics scripts.
- Layout Stability: Explicit
widthandheightattributes must be declared on all image tags to prevent cumulative layout shift during browser parsing.
Plain HTML Conformance Matrix:
- Document Type Declaration: Strict adherence to
<!DOCTYPE html>(the current HTML standard). - Character Encoding: UTF-8 declared via
<meta charset="utf-8">in the document head. - Semantic Markup: Use of HTML5 structural elements (
<header>,<nav>,<main>,<article>,<footer>) for proper document outline. - No Dynamic Scripting: Zero client-side JavaScript execution required for primary navigation, visual layout, or document reading.
