I hope you're all enjoying the speed of the site today and yesterday. We're continuing converting all popular and intensive database queries into using our memcached system instead. We're not done, though... we have one last query to convert, and then most of our 20 million+ page views per day won't even hit the databases. Because the databases are generally the limiting factor, involving slow moving parts, removing our dependence on them keeps making the site faster. We've also orded a bunch of new webservers, even though we don't need them. We just know from experience that web node CPU will be the next bottleneck... it always jumps back and forth between web servers and the backend.
