Okay, I need to create a wiki-style document about "Page Speed" under the categories of Technology > Web Development > Technical Element Optimization. Let me start by understanding the requirements.

First, the structure: H1 for the title, an overview section, several sections with H2 and H3 headings, and maybe references or related documents. The content needs to be accurate, detailed, easy to read, and use technical terms with explanations. Also, markdown formatting with proper hierarchy, lists, tables, code blocks if needed, and at least 800 characters.

Starting with the title: "페이지 속도" as H1. Then an introduction explaining what page speed is and its importance in web development. Next sections could be factors affecting page speed, optimization techniques, tools for measurement, best practices, and maybe a conclusion or references.

For the overview section, I should define page speed, mention why it's important (user experience, SEO, conversion rates). Then break down into sub-sections like technical factors, optimization methods, etc. Each H2 can have H3 subsections. For example, under "페이지 속도 영향 요소", maybe list things like server response time, resource size, code efficiency.

In the optimization techniques section, I can talk about image optimization, caching, minification, CDNs, lazy loading. Each of these could be an H2 or H3. Need to explain each technique with examples, maybe some code snippets for minification or CDN setup.

Tools like Google PageSpeed Insights, Lighthouse, WebPageTest should be mentioned. Maybe a table comparing them? Or just list their features and how they help measure speed.

Best practices could include using efficient coding practices, reducing HTTP requests, leveraging browser caching. Also mention the importance of mobile optimization since many users access via mobile devices.

Need to ensure that technical terms are explained. For example, "CDN" should be briefly defined as a content delivery network that distributes content through servers worldwide to reduce latency.

Check for accuracy: Make sure the information about how each technique improves speed is correct. For instance, minifying CSS/JS removes unnecessary characters, which reduces file size and load time. Lazy loading defers image loading until needed, saving bandwidth and improving initial load speed.

Also, include some statistics or examples if possible. Like "A 1-second delay in page response can result in a 7% reduction in conversions" – though I need to verify that data.

Avoid being too technical without explanation. For example, when talking about HTTP/2 or HTTP/3, explain what they are and how they improve speed compared to older versions.

Make sure the document flows logically from introduction to factors, techniques, tools, best practices, and conclusion. Each section should build on the previous one.

Check for markdown formatting: Use # for H1, ## for H2, ### for H3. Lists with hyphens or numbers. Code blocks for any example code. Maybe a table for tools with their descriptions.

Length: Need to hit at least 800 characters. The current draft seems to be around that, but I should check each section's length. If needed, expand on certain points with more details or examples.

Finally, proofread for clarity and correctness. Ensure that all information is up-to-date, especially regarding tools and technologies. For example, confirm that Lighthouse is still a relevant tool and how it integrates with Chrome DevTools.
