Glossary:

First Byte Time	Applicable Objects	Time to First Byte for the page (back-end processing + redirects)
First Byte Time	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)
Keep-Alive	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*"
GZIP Text	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	Any object with a mime type of "image/*"
Compress Images	What is checked	GIF - All pass PNG - Must be 8 bit or lower (no 24-bit PNGs will pass) JPEG - 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.
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"
Cache Static	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 than 30 days you will get a warning (only applies to max-age currently).
Combine CSS/JS	Applicable Objects	All css and javascript objects
Combine CSS/JS	What is checked	If multiple files of the same type are served then each additional css file beyond 1 will subtract 5 percent and each Javascript file beyond the first wil subtract 10 percent
Use A CDN	Applicable Objects	All static non-html content (css, js and images)
Use A CDN	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
Minify JS	Applicable Objects	All html, javascript and json responses
Minify JS	What is checked	Javascript will be run through jsmin. If the original content was gzip encoded, the minified version will also be gzipped for comparison. If > 5KB or 10% is saved then it will fail. If > 1KB is saved, it will warn, otherwise it will pass.
Cookies	Applicable Objects	All requests
Cookies	What is checked	Any request for a static object that sends up a cookie will fail. All other requests that send up cookies will warn.
