How this service works
Prüft am Objekt stylesheet den Befund Verbindungsaufbauzeit.
Output
Returns a performance finding (Befund) describing the measured connection establishment time for the target stylesheet resource, including timing data and potentially a pass/fail or benchmark comparison.
Example use cases
Diagnosing slow page load from CSS
“My site at https://shop.example.com is loading slowly — can you check the connection time for the stylesheet at https://cdn.example.com/styles/main.css to see if that's part of the problem?”
Third-party stylesheet latency audit
“We're using a stylesheet from a third-party CDN at https://fonts.thirdparty.com/styles/bundle.css — can you measure the connection establishment time for it so I know if it's adding latency?”
Performance regression check after deploy
“After our latest deploy, can you test the connection time for the stylesheet https://myapp.com/dist/app.css to see if something changed with our server's connection handling?”
Technical details
Endpoint
POSThttps://tempo.halowerk.com/v1/pruef/tempo/verbindungszeit/stylesheetWhen to prefer
Use this endpoint when you specifically need to measure the TCP/TLS connection establishment time for a stylesheet (CSS) resource, as opposed to other resource types (images, scripts, fonts, iframes, video). Choose this over general page speed tools when you want programmatic, per-resource-type connection latency data that can be integrated into automated audits or monitoring pipelines.
Side effects
- Target URL is unreachable or returns a non-2xx response — endpoint may return an error or null timing result
- Provided URL does not point to a stylesheet resource — result may be meaningless or return an error
- CSS selector matches no element or multiple elements — first match or error is returned
- URL exceeds 2048 character limit — request validation failure
- Invalid user_agent pattern — request rejected with validation error
