www.infineon.com speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 15:51 UTC. Grade B (86/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 81 ms 33%
- TCP connect 32 ms 13%
- Server wait 133 ms 54%
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 246 ms. That is workable, and the cheapest win left is caching or a warmer connection.
- The page transfers 874.1 KB over 26 request(s). Images files are 72% of it, so resize and recompress the largest images before anything else.
- The HTML itself arrives gzip-compressed.
- It runs over HTTP/3, so the assets share a connection instead of opening one each.
- 71% of the weight comes from other hosts (analytics, fonts, embeds), which also means their slow day becomes your slow day.
- The largest element painted at 932 ms, inside the 2.5 s Google calls good.
- Layout stayed still (CLS 0.004), so nothing jumps under the reader's cursor.
- The main thread was blocked for 24 ms in total, which is not enough to feel.
Fix first: Render-blocking resources - Add defer or async to scripts that do not change the first paint, inline the critical CSS, and load the rest with media="print" plus an onload swap.
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, 874.1 KB across all of them.
Top issues
Render-blocking resources
high impact7 render-blocking resource(s) in the document head (3 script(s), 4 stylesheet(s)). The page cannot paint until each one arrives.
Fix: Add defer or async to scripts that do not change the first paint, inline the critical CSS, and load the rest with media="print" plus an onload swap.
Image delivery and format
medium impact0 image(s) over 200 KB and 2 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.
Cache static assets
medium impact11 asset(s) answer without a Cache-Control max-age, so browsers revalidate them on every visit.
Fix: Version filenames on change and serve them with a long max-age plus immutable. That is what makes a returning visitor fast.
Third-party weight
medium impact2 third-party host(s) serve 624.3 KB of this page. Each one is another DNS lookup, TLS handshake and point of failure you do not control.
Fix: Self-host the libraries you can, drop the tags you cannot justify, and preconnect the ones you keep.
HTML document size
medium impactThe document transfers 99.5 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.
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
