Talk #1: Profiling PHP applications everywhere, all the time
by Marc Weistroff, CTO at Blackfire

Modern application development involves multiple environments where different states of the code live. The production environment is where the most stable version run, while the staging & development environments host on-going developments. We'll see how we can continuously profile each environments & how we can catch performance issues before they impact the production system.

Talk #2: Tracing: Flame graphs of your production PHP
by Sammy Kaye Powers, Open Source Engineer at Datadog

After profiling & benchmarking our PHP apps locally, we often push to production with confidence that the app will perform optimally. But aside from a few logs & some basic memory & CPU stats from the hosting provider, we might not have much visibility into the production stack. Using the new PHP tracer extension from Datadog, we can get more visibility into the production stack; from high-level views showing how services interact, to flame graphs of PHP applications that illustrate bottlenecks & stack traces from intermittent 500 errors. In this talk I'll show you how the Datadog PHP tracer can give you visibility into production & we will even get a little peek of how the tracer works under the hood.

Talk # 3: Developing cacheable PHP applications
by Thijs Feryn, Technical Evangelist at Varnish Software Group

Most of us are familiar with HTTP, but when it actually comes to creating cacheable web content, there is still a lot to be learned.

In this presentation I will show you how to leverage specific mechanism to achieve a good hit rate without losing touch with some of the challenges of real-life web projects.

Keywords: cache control, cache variations, conditional requests, stateful content, HTTP fragments, cache invalidation & edge-side logic.

The goal is to empower developers to control the behavior of reverse caching proxies like Varnish, Content Delivery Networks, or even browser cache, using the power of HTTP.
