At Tag1 Consulting we do a lot of work on increasing web site performance, especially around Drupal sites. One of the common tools we use is memcached combined with the Drupal Memcache module. In Drupal, there are a number of different caches which are stored in the (typically MySQL) database by default. This is good for performance as it cuts down on potentially large/slow SQL queries and PHP execution needed to display content on a site.

I see a lot of people coming by #centos and similar channels asking for help when they’re experiencing a problem with their Linux system. It amazes me how many people describe their problem, and then say something along the lines of, “and I disabled SELinux...”. Most of the time SELinux has nothing to do with the problem, and if SELinux is the cause of the problem, why would you throw out the extra security by disabling it completely rather than configuring it to work with your application?
