zenweb.proofpoint.com/urldefense?locale=en-US speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 13:18 UTC. Grade A (93/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 78 ms 19%
- TCP connect 96 ms 24%
- Server wait 229 ms 57%
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 403 ms. That is workable, and the cheapest win left is caching or a warmer connection.
- The page transfers 9.5 KB over 1 request(s), which is lean.
- The HTML itself arrives gzip-compressed.
- It runs over HTTP/3, so the assets share a connection instead of opening one each.
- The largest element painted at 476 ms, inside the 2.5 s Google calls good.
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.

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.
Top issues
Server response time (TTFB)
high impactThe first byte arrived after 403 ms. Of that, 229 ms was the server thinking and 174 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.
TLS certificate validity
high impactThe certificate for zenweb.proofpoint.com has 19 day(s) left.
Fix: Renew automatically (certbot with a working renewal timer) and alert on the certificate, not on the renew command, so a silent failure is caught weeks before a browser warning.
Avoid extra redirects
medium impact1 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.
