iterable.com speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 13:32 UTC. Grade A (95/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 76 ms 39%
- TCP connect 24 ms 12%
- Server wait 93 ms 48%
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 server answered in 193 ms, which is fast: almost all of the wait is the page itself, not the host.
- The page transfers 121.4 KB over 26 request(s).
- The HTML itself arrives gzip-compressed.
- It runs over HTTP/3, so the assets share a connection instead of opening one each.
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.
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, 121.4 KB across all of them.
Top issues
Render-blocking resources
high impact7 render-blocking resource(s) in the document head (0 script(s), 7 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.
HTML document size
medium impactThe document transfers 103.2 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
