I'm sorry but I cannot take this article seriously. Memcached is trivial to install and to set up on all the Linux distributions that I know of. On Ubuntu, it's actually as simple as apt-get install -y memcached. I have set up memcached servers that handle tens of thousands of queries per second and it has never been a concern. In any event, you're much better off doing full-page caching using tools designed for this task, such as Varnish. As a bonus, you get tools such as varnishtop, varnishlog and varnishstat to monitor your cache.
