www.sephora.com speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 14:24 UTC. Grade B (81/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 85 ms 31%
- TCP connect 35 ms 13%
- Server wait 150 ms 56%
Measured on the connection that fetched the HTML. Every other request on the page waits for the end of this bar before it can start.
How this page compares
Every report published here is in this comparison, so it is a reference population of pages tested from one server - not a benchmark of the whole web.
What these numbers mean
- The first byte arrived in 270 ms. That is workable, and the cheapest win left is caching or a warmer connection.
- The page transfers 2.56 MB over 26 request(s). Javascript files are 78% of it, so defer what is not needed for the first screen, and drop tags nobody uses.
- The HTML itself arrives br-compressed.
- It runs over HTTP/3, so the assets share a connection instead of opening one each.
- The largest element painted at 212 ms, inside the 2.5 s Google calls good.
Fix first: Total page weight - Work through the heaviest assets first: images, then fonts, then third-party scripts.
Read on one shared server, not a visitor's phone: use it to compare pages against each other, not as a promise about every connection. We fix what these tests find.
Screenshot
What the page looks like
Loaded in headless Chromium on this server. Click an image to open it full size.
Browser render
The same URL loaded in a real browser, so these are the readings curl cannot produce. The grade above is still built from the server measurements.
Page weight by type
What the page is made of
Transfer size, compressed as sent. 26 request(s) in total, 2.56 MB across all of them.
Top issues
Total page weight
high impactThe page transfers 2.56 MB across 26 request(s), with the document itself at 174.9 KB.
Fix: Work through the heaviest assets first: images, then fonts, then third-party scripts.
Image delivery and format
medium impact0 image(s) over 200 KB and 1 large image(s) still served as JPEG or PNG.
Fix: Serve WebP or AVIF with a JPEG fallback, size images to the space they occupy, and lazy-load anything below the fold. Images are usually more than half of a slow page.
HTML document size
medium impactThe document transfers 174.9 KB. A bloated document delays every other request, because nothing else can start until it is parsed.
Fix: Paginate long listings, move repeated markup into a template, and stop inlining large data URIs into the HTML.
JavaScript weight
medium impact3 JavaScript file(s) over 200 KB: main.bundle.B25CoriginmasterD20261019185102.js (1.07 MB), commons.chunk.B25CoriginmasterD20261019185102.js (359.7 KB), priority.chunk.B25CoriginmasterD20261019185102.js (249.3 KB)
Fix: Split routes, remove unused dependencies, and prefer a two-file build (one pinned library, one application bundle) over many small ones.
Avoid extra redirects
medium impact1 redirect hop(s) before the page load started, each one a full round trip before the first byte.
Fix: Link to the canonical URL (and make sure http, the apex domain and www all point at it) so no visitor pays a redirect first.
Waterfall
Slowest requests
Each bar is one request's own response time, scaled to the slowest. Assets were fetched in parallel, so the bars overlap in real time rather than stacking. first party third party
