A request for a faster screen can easily begin with cache or server changes. K-POP PULSE’s August 6 optimization record separates response measurements from HTML composition first. Desktop and mobile navigation rendering the same subjects twice became a concrete target.
I do not use this story to promote the current website’s speed. It compares the historical before-and-after document with actual template and JavaScript edits, including a correction to the initial expected values. Measurement scope needed maintenance alongside the implementation.
Uniform responses can coexist with extra screen work
The document first records similar response timing across routes and edge-cache hits, then examines the subject page’s uncompressed HTML composition. That supported inspecting duplicate markup instead of automatically changing the server or cache again.
It also states that cache URL normalization meant the measurement did not isolate origin performance. A query parameter alone should not be assumed to bypass that cache. Keep the measured route, environment and observed response with the number to retain its limits.
Hidden lists were still two rendered copies
The early template runs the same collection through mobile and desktop loops separately. CSS can choose which is visible while both sets remain in HTML. Comparing the old string with the actual edit establishes duplication in rendering, beyond speculation about a slow screen.
Visibility and generation are different states. An element being hidden does not establish that its data or image tags were never generated. Nor is every hidden element necessarily redundant. Compare whether the elements share a responsibility or provide genuinely distinct states before removing one.
Combining the list required changing state handling too
The August 6 edit creates one nav with CSS choosing its horizontal or vertical direction. JavaScript moves from locating two elements to reading actual flex-direction. Another edit preserves separate position keys for horizontal and vertical browsing. It does not leave interaction code searching for the old elements after shrinking the markup.
The new explanatory skeleton illustrates rendering once. In an integration, inspect the event target, selected identity, scroll axis, storage keys and content spacing around the breakpoint. Preserving the site’s intended appearance and behavior remains a separate integration check.
Explore the implementation
New explanatory skeleton; not a recovered template or the historical benchmark.
<nav class="subject-rail" aria-label="Subjects">
<!-- Render each subject once with its stable data-id. -->
</nav>
.subject-rail { display:flex; flex-direction:row; overflow:auto; }
@media (min-width: 900px) {
.subject-rail { flex-direction:column; max-height:20rem; }
}
/* This new skeleton is not the original template or a measured benchmark. */Read before-and-after values within the same comparison
The document’s local comparison reports subject-page HTML changing from 196KB to 154KB and image tags from 285 to 190. These belong to that historical comparison. They are not the current size of the entire site or a measured experience for worldwide visitors.
Earlier composition rows contain other observations, so I do not merge all values into one identical sample. Uncompressed HTML, transferred bytes and tag count are also different measures. A performance explanation needs the comparable conditions to remain attached to its figures.
Correcting the target was part of the work
The initial template comment describes 82KB and roughly 230 duplicate avatars. The optimization document later corrects the calculation of removable material and the original acceptance target. I did not carry that larger, superseded comment into the result.
It also notes that a further reduction would require a separate change to list length or rendering time. Duplicate removal should not inherit the benefits of reductions or deferred rendering that were not implemented. Those next decisions need their own costs and subject-equality conditions evaluated.
Share code together with its verification scope
The new single-rail module develops the historical choice without claiming to reproduce its performance results. Its package includes core checks for identity, axis positions and storage failure. Fresh rendered interaction review remains separately pending.
For a new comparison, retain the same data and route, inspect HTML, list copies and image tags, then follow selection and scrolling. A single rendered list and comfortable reading need different checks. I want the record to support another maker’s repeatable inspection beyond one reduction figure.
