Got upset by the #phpunit testsuite "hanging" for 10s before executing even a single test involving our app. This has been like that for too long I said to myself.

Instead of blindly var_dump() -ing around I used #xdebug traces to find where the issue was.

A nice #flamegraph led me to the culprit: MySQL "truncate table" taking 80% of the time 🙈

Thanks @derickr for your work (and how-to videos)!

Was it ever a goal of software development to make something as fast & narrowly functional as possible while turning the innards of it to code soup?

No?

Then why is this ridiculous #AI #xdebug fork in my LinkedIn feed? 😮‍💨

Came across this repository and was wondering if this is legit or just some random ai work: https://github.com/pronskiy/php-debugger

I also think this is for @derickr

Wenn es um Performance-Debugging geht, gibt es eine Menge verfügbarer Werkzeuge. In den letzten Jahren habe ich nach einem gesucht, das wirklich leicht verwendbar ist und Engpässe selbst gut erkennt.

Es gibt einige, die spezifisch für WordPress sind, beispielsweise als Plugins, und einige für generelles Performance-Debugging in PHP. Andere wiederum benötigen eine bestimmte PHP-Erweiterung. Im folgenden Artikel decke ich alle möglichen Typen ab.

When it comes to performance debugging, there are a wide variety of tools available. The last years, I searched for one that is actually easily usable and provides easy access in identifying bottlenecks.

There are some that are specific to WordPress, e.g. as plugins, some allow general performance debugging via PHP and some require a PHP extension to be loaded. I’ll cover all of these types in the following article.

I'm thrilled to announce that I'll be speaking at the 23rd edition of #phpday, the international PHP conference in Italy, organised by @grusp.

I’ll be presenting a talk titled: "Better Debugging With Xdebug".

It's in Verona, Italy, on May 14-15th 2026.

#PHP #Xdebug #Debugging

Last year I visited 2 big European CMS #flagship events.

One where a talk about sustainability was scheduled in a side event in a basement.
The other where a talk about this was scheduled in the regular main event scheme featuring a joint presentation from Drupal and Typo3 folks.
Also, in this the second event, had presentationf by #PHPUnit (Sebastian Bergman) and #xDebug (Derick Rethans).

Want to guess the #openSource #CMS - names from both events?

Me: "Why won't this app break on this line!?"

Also me: Helps to have #xdebug enabled if you're trying to debug something
