      Glossary

      First Byte Time
      • Applicable objects: Time to First Byte for the page (back-end processing + redirects)
      • What is checked: The target time is the time needed for the DNS, socket and SSL negotiations + 100ms. A single letter grade will be deducted for every 100ms beyond the target.
      Keep-Alive
      • Applicable objects: All objects that are from a domain that serves more than one object for the page (i.e. if only a single object is served from a given domain it will not be checked)
      • What is checked: The response header contains a "keep-alive" directive or the same socket was used for more than one object from the given host
      GZIP Text
      • Applicable objects: All objects with a mime type of "text/*" or "*javascript*"
      • What is checked: Transfer-encoding is checked to see if it is gzip. If it is not then the file is compressed and the percentage of compression is the result (so a page that can save 30% of the size of it's text by compressing would yield a 70% test result)
      Compress Images
      • Applicable objects: JPEG Images
      • What is checked: Within 10% of a photoshop quality 50 will pass, up to 50% larger will warn and anything larger than that will fail. The overall score is the percentage of image bytes that can be saved by re-compressing the images.
      Use Progressive JPEGs
      • Applicable objects: All JPEG Images
      • What is checked: Each JPEG image is checked and the resulting score is the percentage of JPEG bytes that were served as progressive images relative to the total JPEG bytes.
      Cache Static
      • Applicable objects: Any non-html object with a mime type of "text/*", "*javascript*" or "image/*" that does not explicitly have an Expires header of 0 or -1, a cache-control header of "private", "no-store" or "no-cache" or a pragma header of "no-cache"
      • What is checked: An "Expires" header is present (and is not 0 or -1) or a "cache-control: max-age" directive is present and set for an hour or greater. If the expiration is set for less 7 days you will get a warning. If the expiration is set for less than 1 hour you will get a failure. This only applies to max-age currently.
      Use A CDN
      • Applicable objects: All static non-html content (css, js and images)
      • What is checked: Checked to see if it is hosted on a known CDN (CNAME mapped to a known CDN network). 80% of the static resources need to be served from a CDN for the overall page to be considered using a CDN. The current list of known CDN's is here.
