Modules that break Varnish caching, and how to fix them

Power up Drupal search with Jetty & Apache Solr in Ubuntu 10.04

If you are running a big site with loads of visitors or just running a normal site with very minimal resources your basic Drupal search functionality might slow down your site significantly. And it's not even very efficient solution to search all the contents of your site. Don't worry, the help is here.
