Performance is a critical aspect of modern web applications. Recent developments in hardware, software, infrastructure, bandwidth, and connectivity have raised expectations about how the web should perform.

Increasingly this attitude is applied to internal line of business apps, and niche sites, as much as to large public-facing sites. Google even bases your search ranking in part on how well your site performs. Being slow is no longer an option.

Unfortunately, problems can occur at all layers and in all components of an application: database, back-end code, systems integrations, local and third party services, infrastructure, and even – increasingly – the client.

Complex apps often have problems in multiple areas. How do you go about tracking them down and fixing them? Where do you begin?

The answer is you deploy the right tools and techniques. The good news is that generally you can do this without changing your development process. Using a number of case studies I’m going to show you how to track down and fix performance issues. We’ll talk about the tools I used to find them, and the fixes that resulted.

That being said, prevention is better than cure, so I’ll also talk about how you can go about catching problems before they make it to production, and monitor to get earlier notification of trouble brewing.

By the end you should have a plethora of tools and techniques at your disposal that you can use in any performance analysis situation that might confront you.
