How this service works
Prüft am Objekt bild den Befund Verbindungsaufbauzeit.
Output
Returns a performance finding (Befund) indicating the measured TCP/TLS connection setup time for the specified image resource, including the raw timing value and an assessment of whether it is within acceptable bounds.
Example use cases
Hero image connection latency audit
“Check how long it takes to connect to our homepage hero image at https://www.myshop.com/assets/banner.jpg — I want to know if the connection setup time is a bottleneck.”
Third-party image CDN performance check
“Test the connection setup time for the product image hosted at https://cdn.partner.com/product123.png — we're seeing slow page loads and I suspect the external image host.”
Automated image performance monitoring
“Run a connection setup time check on the image at https://blog.mysite.com/wp-content/uploads/thumbnail.webp so I can track whether our server's response is getting slower over time.”
Technical details
Endpoint
POSThttps://tempo.halowerk.com/v1/pruef/tempo/verbindungszeit/bildWhen to prefer
Use this endpoint specifically when you need to isolate and measure the TCP/TLS connection setup time for an image resource (not a full page, script, font, or video). It is ideal for diagnosing slow connection establishment to image hosts or CDNs, and for automated performance auditing of individual image assets. Choose sibling endpoints for other resource types (fonts, scripts, videos) or other timing metrics (TTFB, render start).
Side effects
- Non-public or unreachable image URL returns an error or timeout
- URL does not point to an image resource, leading to invalid test results
- CSS selector matches zero or multiple elements if used with an object input
- Provided address exceeds the 2048-character limit
- User agent string contains invalid characters or exceeds length limit
- Network-level failures or firewalls block the probe connection
