Hello,

I'm currently building site and have noticed that my site is quite slow (average load time 400ms). So I was thinking of a ways to make it faster for anonymous user. I was unable to use normal caching because at least two modules (that is blocks they provide) ubercart and polls are not compatible or are less functional. One way to solve this problem is by using additional ajax request and fill block from there, but that seems to be a messy solution. So, I came to an idea, to do the same thing but without extra ajax request. Another idea was, that not every module is needed for rendering few blocks, so why should all be loaded.

I am preparing to migrate a site with over 19 million nodes and a 2500 term taxonomy vocabulaty from Drupal 5 to 6. While reading up, I have discovered Pressflow and want to consider it. How do I proceed with the upgrade? Can I use the same strategy that I and others have used to migrate sites from Drupal 5 to 6, copying the database, then replacing the Drupal core files with Pressflow's core files? Or will that create a hopelessly broken site to pick up pieces for?

Amazon has announced micro instance, which is cheaper. The sluggish apache2 stack may not work well on this limited resource. So I am planning to install drupal on nginx and sqlite, with custom compited lite php.

I'm in charge of 100 plus drupal sites in use by the Purdue University Professional Writing program. We host sites used by instructors teaching multiple courses in PW as well as this Fall introductory composition. Currently, we are using a single multisite install to host all of these sites, with all the courses running off the main code. We're using Storm On Demand hosting, with their intro level server, which is one core on an intel quad core, with 2gb of ram.
