How this service works
Prüft am Objekt schrift den Befund Verbindungsaufbauzeit.
Output
Returns a performance finding (Befund) for the connection establishment time of the targeted font/text resource, including the measured duration and assessment of the connection phase for the specified Schrift object.
Example use cases
Font CDN connection latency audit
“Run a connection time check on the font file served from https://cdn.example.com/fonts/heading.woff2 — I want to know how long the connection handshake takes before the font actually starts downloading.”
Monitoring font resource performance over time
“I need to track connection establishment time for the Schrift resource at https://myshop.com/assets/fonts/body.woff2 so I can alert if it goes above our SLA threshold.”
Diagnosing slow page render due to font loading
“Our homepage feels sluggish — can you probe the connection time to the font at https://example.com/fonts/main.ttf and tell me if the connection phase is the bottleneck?”
Technical details
Endpoint
POSThttps://tempo.halowerk.com/v1/pruef/tempo/verbindungszeit/schriftWhen to prefer
Use this endpoint when you specifically need to isolate and measure the TCP/TLS connection establishment time for font or text (Schrift) resources, as opposed to total page load time, DNS resolution time, or other performance metrics. Prefer this when diagnosing slow font loading where the connection phase (not DNS or transfer) is suspected as the bottleneck.
Side effects
- Target URL is unreachable or returns a non-2xx status — returns an error or null result
- URL is not a valid public HTTP(S) address — validation error
- CSS selector matches no element or multiple elements (first match used) — may return unexpected result
- Network timeout during connection probing — may return a timeout error
- Invalid user_agent string pattern — schema validation failure
