www.learncbse.in speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 16:28 UTC. Grade B (84/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 61 ms 13%
- TCP connect 18 ms 4%
- Server wait 394 ms 83%
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 473 ms. That is workable, and the cheapest win left is caching or a warmer connection.
- The page transfers 507.9 KB over 17 request(s). Javascript files are 79% 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.
- 71% of the weight comes from other hosts (analytics, fonts, embeds), which also means their slow day becomes your slow day.
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. 17 request(s) in total, 507.9 KB across all of them.
Top issues
Server response time (TTFB)
high impactThe first byte arrived after 473 ms. Of that, 394 ms was the server thinking and 79 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.
Compress text responses
high impact2 text response(s) of 10 KB or more are sent uncompressed, and the document itself is not compressed. That is 213.1 KB 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.
Render-blocking resources
high impact8 render-blocking resource(s) in the document head (5 script(s), 3 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.
Third-party weight
medium impact5 third-party host(s) serve 360.3 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.
JavaScript weight
medium impact1 JavaScript file(s) over 200 KB: adsbygoogle.js (201.2 KB)
Fix: Split routes, remove unused dependencies, and prefer a two-file build (one pinned library, one application bundle) over many small ones.
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
