This session is to discuss some concepts around increasing web-site performance *on the web* - such as nginx, CDNs, memcache, user load cache, authcache, XHProf (memory profiling). If you want to know (or more importantly want to share) some of the best ways to deliver dynamic content - let's talk!

Performance

• CDN
• user load cache
• authcache
• memcache
• (varnish)
