How this service works
Prüft am Objekt stylesheet den Befund Zeit bis zum ersten Byte.
Output
Returns a performance finding for the TTFB (Time to First Byte) of the specified stylesheet resource, including the measured response time and an assessment of whether the value is within acceptable ranges.
Example use cases
Diagnose slow stylesheet delivery
“Our users are complaining about slow page loads — can you measure the TTFB for our main stylesheet at https://shop.example.com/assets/css/app.css and tell me if the server response time is the bottleneck?”
Benchmark competitor CSS performance
“I want to compare how fast our stylesheet loads versus our competitor's — can you measure the Time to First Byte for https://competitor.com/css/main.css and give me the result?”
Monitor CDN-served stylesheet latency
“We just switched our stylesheet to a CDN at https://cdn.mybrand.com/styles/global.min.css — can you check the TTFB to verify our CDN is actually serving it quickly?”
Technical details
Endpoint
POSThttps://tempo.halowerk.com/v1/pruef/tempo/ttfb/stylesheetWhen to prefer
Use this endpoint when you specifically need to measure the Time to First Byte for a stylesheet (CSS) resource, as opposed to measuring TTFB for a full page, video, iframe, or API response. It is the right choice when diagnosing CSS delivery performance, CDN configuration, or server response time for individual stylesheet assets.
Side effects
- Stylesheet URL is not publicly accessible (returns error or connection refused)
- URL points to a non-stylesheet resource, producing irrelevant TTFB data
- Provided URL exceeds 2048 characters or is malformed
- CSS selector matches no element or multiple elements (first match used)
- Target server is too slow and request times out
- Invalid user_agent string pattern causes request rejection
