Yeah, xcache, vboptimise, powerful server, everything setup and tweeked to perfection. The stats dont lie, im still getting the same traffic still as google hasnt dropped the pages yet and load and everything is so low. Old translated content is currently 301'd to english. Must be the translated pages, there is no other explanation.
Im not disputing traffic increases, but check your forum, the mod creates broken pages, broken links all sorts, seriously, check everyone of your pages in a browser. Also, traffic hits is one thing, but is this increasing your posts/threads? is it turning off your regular members, all the foreign content mixed in with english, do you really know the effect it is having on your community other than more hits in server logs.
Id love to see your google wmt stats, what sort of page speed and crawl speed you are getting

As soon as page speed becomes a bigger issue, people running this are going to see some serious traffic drops, big G wont tolerate 10sec page loads. And that is what wmt reports these pages as taking to render. wmt doesnt lie either.
