About KeyCDN Performance Test

The KeyCDN Performance Test checks a single asset, such as a page, image or script URL, from 10 locations around the world at once. For each location it breaks down DNS lookup, connection, TLS and time to first byte, and shows the HTTP response headers.

It suits checking how a server or CDN responds in different regions. It does not load a whole page with its assets; KeyCDN offers a separate Website Speed Test for that.

Strengths

  • Tests from 10 global locations in one run
  • Breaks out DNS, TLS, connection and TTFB times
  • Shows HTTP response headers

Limitations

  • Tests a single asset, not a full page
  • Promotes KeyCDN's paid CDN service
