When using MySQL and InnoDB you will inevitably run into lock timeouts sometime, somewhere. We have recently started seeing this with some of our Shopware 6 customers in their storefronts or worker queues, so I was reminded to go back to 2017 in our codebase when we put a fix in place. In our case, this happened on tables that were constantly written to from many different sources in the code base.

Get the cake, Tideways is turning ten! Exactly on this day ten years ago, we lifted the veil on Tideways’ predecessor and thus began our exciting journey that continues to this day. We would like to celebrate by presenting interesting new features to you. Summary: Don’t miss out on our webinar that will guide you through these new features, taking place July 3rd starting at 3 pm.

PHPs compiler and bytecode cache OPcache not only cache the compile step from PHP source code to virtual machine bytecode, they also include optimizations that can produce faster bytecode: For example PHP can: For PHP 8.4 Tideways sponsored the work of our colleague Tim to add another compiler optimization for the function sprintf().

A few weeks ago, Andrey from Ecommlab contacted me to ask me about a strategy to get performance insights from Tideways into Shopware 6 checkout. The store of our joint customer “Bär Schuhe” was slow for customers during the order confirmation process.

This is the story of the manufacturing of seven-league boots for a function that is responsible for processing XML/HTML data in the PHP library. Optimizations in the PHP standard library, like here in ext/dom, have the potential to speed up the performance of applications significantly by an upgrade to the current PHP version.

You can now unpack the Christmas present that was promised to you at the end of 2023! As you may have already read in the Flamegraph Feature Preview, this exciting new feature of the Profiler is now the focus of our first release in 2024. The Flamegraph complements the Timeline and Callgraph features and visualizes Aggregated Traces. The goal was to provide profiling information across many traces and thereby gaining new and deeper insights into performance.

As a founding member and major contributor to the success of the PHP Foundation, Tideways sponsored the Foundation with 12,000 USD in 2023. As a member of the administrative board of the PHP Foundation, the advancement of the open source language PHP is key for us. In the founding year, we supported the Foundation with 10,000 USD and followed this up in 2022 with another 15,000 USD. As a major sponsor, it is our declared goal to uphold our commitment to PHP and the foundation.

As a Christmas present, we have started rolling out a new feature for the Profiler: flamegraph rendering in addition to the existing Timeline and Callgraph. This is a feature preview and will see more changes in Q1 of 2024. For now, only customers with the most recent plans (Tideways 6) can access them, or you can view them in traces of the „demo“ organization. Let us know what you think of it!

Since our last release announcement in April we have been working on a number of new features for Tideways that we are now happy to share with you. This is the second and final release for 2023. From here the team will be looking ahead to 2024, the 10th anniversary of Tideways’ launch, and preparing some amazing new features and improvements.

90% of the time when I explain how the stat cache works in PHP, people are surprised because they expected it to work differently. It was invented to solve a very limited problem when you call several file system related operations on the same file in quick succession. Why should you know how it works? Because sometimes you need to work around the cache with the clearstatcache() function to get PHP code to run without errors.
