PHP 8.1 Benchmarks - Continuing The Nice Performance Trajectory
Written by Michael Larabel in Software on 28 November 2021. Page 2 of 2. 29 Comments

With the common PHPBench we see quite nicely how PHP has evolved especially well over the past half-decade plus since the introduction of PHP 5.6. PHP 8.0 to 8.1 squeezed out an extra 4% improvement in this benchmarkas another evolutionary step forward and continuing the steady improvements made during the PHP 7.x releases.

While the PHP micro-benchmarks aren't too useful, from these tests they are just another example showing the advancements of PHP over the past number of years.

For our own benchmark with the Phoronix Test Suite itself for exercising various code paths around XML parsing, JSON generation, and other common real-world operations, here is a look at things. With PHP 8.1 is a nice improvement after being largely flat from PHP 7.3 to PHP 8.0 on this AMD EPYC Linux server. Most of the dramatic gains were enjoyed back during late PHP 5.x and early PHP 7.x releases.

Such as the render tests for generating the SVG graphs as being viewed for the results in this article, PHP 8.1 continues moving in the right direction for performance.

Coming a bit of a surprise is PHP 8.1 even having slightly lower peak memory use than prior PHP versions.

That's the quick overview of PHP 8.1 performance, but long story short it's another nice release advancing this server-side programming language. There are some great additions on the language side with PHP 8.1 while from the performance aspect with tests across various systems there are incremental improvements to enjoy and continuing the years-long performance journey that PHP has been on to make it more competitive with other scripting languages.
