rtbwise.com speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 13:40 UTC. Grade A (90/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 96 ms 27%
- TCP connect 71 ms 20%
- Server wait 195 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 362 ms. That is workable, and the cheapest win left is caching or a warmer connection.
- The page transfers 909.8 KB over 13 request(s), which is lean. Images files are 95% of it, so resize and recompress the largest images before anything else.
- It runs over HTTP/3, so the assets share a connection instead of opening one each.
- The largest element painted at 380 ms, inside the 2.5 s Google calls good.
Fix first: Compress text responses - Turn on brotli (preferred) or gzip for text/css, javascript and text/html in the web server. This is the cheapest win available on almost any site.
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. 13 request(s) in total, 909.8 KB across all of them.
Top issues
Compress text responses
high impact0 text response(s) of 10 KB or more are sent uncompressed, and the document itself is compressed. That is 0 B of compressible text.
Fix: Turn on brotli (preferred) or gzip for text/css, javascript and text/html in the web server. This is the cheapest win available on almost any site.
Image delivery and format
high impact1 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.
Total page weight
medium impactThe page transfers 909.8 KB across 13 request(s), with the document itself at 25.6 KB.
Fix: Work through the heaviest assets first: images, then fonts, then third-party scripts.
Strict-Transport-Security
low impactHSTS is not set, so the first visit on a hostile network can still be downgraded to HTTP.
Fix: Send Strict-Transport-Security with a max-age of at least six months. Add includeSubDomains once every subdomain is HTTPS.
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
