How this service works
Prüft am Objekt bild den Befund TLS-Aushandlungszeit.
Output
Returns a performance finding (Befund) for the TLS negotiation time (TLS-Aushandlungszeit) measured against the image object (bild) at the specified URL. The response includes the measured timing metric indicating how long the TLS handshake takes for that image resource.
Example use cases
Image CDN TLS performance audit
“I'm using a CDN for images on https://shop.mystore.com — can you measure the TLS negotiation time specifically for the image assets on that page so I can see if the SSL handshake is slowing things down?”
Diagnosing slow image loads on landing page
“Our landing page at https://landing.mybrand.com feels slow and I suspect it might be TLS overhead on the images. Can you check the TLS negotiation time for the image objects there?”
Monitoring TLS image performance after server migration
“We just migrated our server and I want to verify that TLS handshake times for images on https://newsite.example.com are still acceptable — can you run a TLS negotiation time check on the image assets?”
Technical details
Endpoint
POSThttps://tempo.halowerk.com/v1/pruef/tempo/tls-zeit/bildWhen to prefer
Choose this endpoint when you specifically need to measure TLS negotiation time for image assets on a webpage, as opposed to general page-level TLS metrics or TLS timing for other resource types (scripts, stylesheets, fonts). It is ideal for diagnosing whether SSL/TLS handshake latency is a bottleneck specifically in image loading performance. Use sibling endpoints for other resource types or other timing metrics.
Side effects
- Target URL is unreachable or returns non-2xx status
- URL does not serve image content, making the image-specific metric inapplicable
- CSS selector matches zero or multiple elements when only one is expected
- Invalid or non-public URL (e.g. private IP, localhost)
- TLS not applicable because URL uses HTTP only
- DNS resolution failure for target domain
- Request timeout if server is too slow to respond
