Since I still have render time anywhere between 1 to 8s:
--> 1.4s http://www.webpagetest.org/result/101016_85SM/
--> 3.5s http://www.webpagetest.org/result/101016_85SP/
--> 8s http://www.webpagetest.org/result/101016_85T1/
, even after fastcgi was enabled, my host suggested to install eAccelerator. It sounds good in principle (caching php compilation) but I was wondering if this would interfere with W3? Should I go for it? Any advice would be appreciated.
p.s. to Frederick: I emailed you a couple of days ago regarding how much you would charge for optimizing my server. Can you get back to me please? Thanks.
