Not every problem should be solved with PHP. For certain types of applications it’s simply more appropriate to select a different programming language. You might be glad to hear that parsing binary data, is **NOT** one of them. If you don’t have to worry about microseconds and the biggest concern is development time, PHP might be in fact a very good tool for the job.

A single-page application (SPA) was something I’ve been exploring for the last few months. I always liked the idea of moving certain responsibilities to the client’s side. After all, why would you like to waste server’s RAM/CPU to buil a HTML page (and pay for a transfer to deliver it) when a web browser is perfectly capable of doing that on its own? You will not only save money but also provide a better user experience. In addition to the performance, moving the presentation layer to the web browser gives a clearer division between back-end and front-end code.

Nevertheless I will try to give a comprehensive answer which hopefully is going to be useful not only to the beginners but also to the people with some commercial experience.

In my previous post I showed how to integrate Varnish Cache with a PHP application. The example can solve various simple problems but it might not be enough for a complex software. A good example is a multilingual application. One URL can have multiple caches. You might also need to know more about a user (is he logged in? has he received a notification? etc) to make some additional caching decisions.

Varnish Cache is a web application accelerator. It stands in front of a web server and can cache any type of data. It stores data in memory and can speed up your application by a factor of 300-1000x depending on your architecture.

Developers care about performance of their software. The problem is that they don’t usually have enough time for a proper optimisation. I would like to propose 3 relatively simple steps which won’t take much time and will improve a response time by at least 60%.
