In this blogpost we'll take a quick look at how Blackfire is set-up and how Lambda layers works. In the second part of this post we'll add the two together to get production profiling data from Lambda into Blackfire.

Collin O' Dell, member of the PHP League, shares how he was able to significantly improve the performance his json5 package using Blackfire profiling.
Back in November I released colinodell/json5 - a JSON5 parser for PHP. It's essentially a drop-in replacement for PHP's json_decode() function, but it allows things like comments, trailing commas, and more.

I always knew that a PHP-based implementation would be slower than PHP's native C implementation, but execution time measured in minutes was completely unacceptable!
So I fired up Blackfire (which I've previously used to optimize league/commonmark) and got to work.

Marko Lekić explains how he used Blackfire.io to solve a performance problem in one of his long running Laravel console commands.
https://medium.com/@marlek/getting-rid-of-laravel-models-to-improve-performance-of-the-command-blackfire-io-profiling-53884fa6573eThe command worked, but very slowly. We left it working like that for some time until we finished critical stuff in the system and had time to go back and refactor some slow running code.
We ran the command with Blackfire.io and saw some interesting information when we ordered functions by percentage of exclusive time.
For the League's CommonMark parser, we chose to prioritize extensibility over performance. This led to a decoupled object-oriented design which users can easily and customize. This has enabled others to build their own integrations, extensions, and other custom projects.http://www.colinodell.com/blog/2015-11/optimizing-league-commonmark-blackfire-ioThe library's performance is still decent - the end user probably can't differentiate between 42ms and 2ms (you should be caching your rendered Markdown anyway). Nevertheless, we still wanted to optimize our parser as much as possible without compromising our primary goals. This blog post explains how we used Blackfire to do just that.
