*This is a 15-minute Lightning Talk*

It’s the bug report call we all dread: “the website is slow.” None of the code has changed in weeks and, other than writing a few new blog posts, the client hasn’t touched the site. The website has been running fine for months. So why is it running slow now? Is it the database? The web server? Is your server swapping? Does it have anything to do with your application or is it maybe a third party service that’s running slow, like DNS? Although we won’t be able to go over everything that might cause your server to behave badly, this talk will review the basics of profiling your server in order to diagnose problems. No prior knowledge of command line tools will be assumed, and the talk will be accessible to non-developers. The one thing that attendees should be familiar with prior to attending this talk is how to SSH into their server. It would also be a good idea for attendees to know how to install software packages using apt or yum.
