adelaide.edu.au speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 15:15 UTC. Grade C (73/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 268 ms 57%
- TCP connect 50 ms 11%
- Server wait 148 ms 32%
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 467 ms. That is workable, and the cheapest win left is caching or a warmer connection.
- The page transfers 2.65 MB over 26 request(s). Images files are 98% of it, so resize and recompress the largest images before anything else.
- The HTML itself arrives br-compressed.
- It runs over HTTP/3, so the assets share a connection instead of opening one each.
Fix first: Server response time (TTFB) - Cut server think time: page cache, query indexes, fewer synchronous calls to third parties inside the request. Connection setup is distance, so a nearer region or a CDN edge helps instead.
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.
The headless browser did not capture this page when the test ran, so only the server measurements are shown.
Page weight by type
What the page is made of
Transfer size, compressed as sent. 26 request(s) in total, 2.65 MB across all of them.
Top issues
Server response time (TTFB)
high impactThe first byte arrived after 467 ms. Of that, 148 ms was the server thinking and 318 ms was connection setup. A first byte under 400 ms is what a visitor feels as instant.
Fix: Cut server think time: page cache, query indexes, fewer synchronous calls to third parties inside the request. Connection setup is distance, so a nearer region or a CDN edge helps instead.
Image delivery and format
high impact3 image(s) over 200 KB and 5 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.
Render-blocking resources
high impact10 render-blocking resource(s) in the document head (4 script(s), 6 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.
Total page weight
high impactThe page transfers 2.65 MB across 26 request(s), with the document itself at 48.4 KB.
Fix: Work through the heaviest assets first: images, then fonts, then third-party scripts.
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
