March 27, 2014: Linux Performance Tools
Chris “Mac” McEniry
It’s 3am and your production website is “slow”. Welcome to the wonderful
world of troubleshooting on Linux.
Here’s a whirlwind 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 with the subsystems that are impacted so you can
appropriately focus on what changes you need to fix it.
