Preface

Now and then you have to create a new project repository, run that git init command locally and kick off a new awesome project. I have to admit I like the feeling of starting something new; it's like going on an adventure!

Building an Image Gallery Blog with Symfony Flex: the Setup

In the previous chapter , we demonstrated how to set up a Symfony project from scratch with Flex, and how to create a simple set of fixtures and get the project up and running.

Building an Image Gallery Blog with Symfony Flex: Data Testing

Throughout the past few months, we've introduced Blackfire and ways in which it can be used to detect application performance bottlenecks. In this post, we'll apply it to our freshly started project to try and find the low-points and low-hanging fruit which we can pick to improve our app's performance.

PHP-level Performance Optimization with Blackfire

One very simple yet very useful tool is query profiling. Enabling profiling is a simple way to get a more accurate time estimate of running a query. This is a two-step process. First, we have to enable profiling. Then, we call show profiles to actually get the query running time.

MySQL Performance Boosting with Indexes and Explain

In this article, we'll analyze our gallery application using the tools we explained in Performance Tools , and we'll look at possible ways to further improve its performance.

Improving Performance Perception with Pingdom and GTmetrix

We've been building a sample application — a multi-image gallery blog — for performance benchmarking and optimizations. At this point, our application serves the same image regardless of the resolution and screen size it's being served in. In this image resizing tutorial, we'll modify it to serve a resized version depending on display size.

Improving Performance Perception: On-demand Image Resizing

In the previous chapter, we've added on-demand image resizing . Images are resized on the first request and cached for later use. By doing this, we've added some overhead to the first load; the system has to render thumbnails on the fly and is "blocking" the first user's page render until image rendering is done.

Using Background Processing to Speed Up Page Load Times

Let's continue optimizing our app. We're starting with on-the-fly thumbnail generation that takes 28 seconds per request, depending on the platform running your demo app (in my case it was a slow filesystem integration between host OS and Vagrant), and bring it down to a pretty acceptable 0.7 seconds.

Server-side Optimization with Nginx and pm-static

As we can see in this report , our site's landing page loads very quickly and generally scores well, but it could use another layer of caching and even a CDN to really do well.
