A good web-performance practice is to make web assets that rarely change to be cached for a very long time. By increasing the "cacheability" of a site, it's performance / speed will naturaly increase. The web assets (think all css, js, fonts and iconography) of your site can typically be cached in a CDN, Apache Dispatcher and most importantly on the client's browser. The longer the better.
This project transparently adds a versioned fingerprint to all configured paths (usualy your design/clientlibs path) and rewrites all html output to reference these assets via the fingerprinted URL. For example suppose you house all your iconography, css and js of your site in "/etc/designs/weretail". When configured, any html output genereated by AEM will rewrite your css, js links from /etc/designs/weretail/clientlibs/core.css to /etc/designs/weretail/v-9-v/clientlibs/core.css where the /v-9-v/ is the unique fingerprint that will change on every deployment. Any iconography, fonts etc references from the css / javascript should use relative path and thus all iconography will also benefit from being able to be cached forever.
