In my case using pagespeed increase page load with +1second and with some high CPU Memory resource costs and disabled it forever. So i think much better is to use xcache for opcode and memcache for variable, sessions and other things. Pagespeed is ok for blogs, websites, but not for forums. I Have over 3000 visits per day with 19.000-20.000 pages views and Pagespeed is not an solution for me, now i'm using xcache+memcache, and i think i will make some proxy cache for index, /forums/ , /categories/ paths to save as static.
