Hi, We have site serving dynamic random() content to users, Also we have a login session where registered users login to see their account then move to normal content pages Ads ( from affiliate networks), Close to million products ( affiliate ) and Vendor info ( close to a millions) So db is very large and heavy and taking all load. Right now optimisation of pages is going on and have used sql and apache cache But speed of loading is still like 6-7 secs. We need to convert and have to cut the seconds to 3-4. HOw do we implement cache varnish with nginx ( most have suggested combination) or one of the 2 in front of apache cache Please suggest also what you can do best option need to explain this properly then will finalise. Please only cache ( varnish, nginx) experts Can pm site name. Regards Rajiv
