www.f-secure.com/us-en speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 16:17 UTC. Grade B (83/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 84 ms 36%
- TCP connect 40 ms 17%
- Server wait 111 ms 47%
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 235 ms. That is workable, and the cheapest win left is caching or a warmer connection.
- The page transfers 113.4 KB over 26 request(s). Images files are 52% 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.
- 63% of the weight comes from other hosts (analytics, fonts, embeds), which also means their slow day becomes your slow day.
Fix first: Avoid extra redirects - Link to the canonical URL (and make sure http, the apex domain and www all point at it) so no visitor pays a redirect first.
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, 113.4 KB across all of them.
Top issues
Avoid extra redirects
medium impact2 redirect hop(s) before the page load started, each one a full round trip before the first byte.
Fix: Link to the canonical URL (and make sure http, the apex domain and www all point at it) so no visitor pays a redirect first.
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
