It's 3am and your production website is "slow". Welcome to the wonderful world of troubleshooting on Linux.
Here's a worldwind tour of the standard system tools to try to understand what "slow" means, where the "slowness" is coming from, so that you can ultimately see why it's slow and how to fix it. Focus will be on how to invoke them, reading their results accurately, and connecting that information with the subsystems that are impacted so you can appropriately focus on what changes you need to fix it.
