Programming language PHP 8 is out: This new JIT compiler points to better performance. As Lua’s JIT supports ARM64, we work with PHP developers to enable and to tune the Opcache JIT in PHP-8 to get the best performance on AWS Graviton processors." Tracing JIT, the most promising of the two, shows about 3 times better performance on synthetic benchmarks and 1.5–2 times improvement on some specific long-running applications. With micro-benchmarks, PHP 7.4 has enhanced its performance even compared to last year version. PHP8: Benchmarking the Symfony Demo App with and without JIT, it has just been introduced and will most likely be improved further in the future, so it might improve our setups after all, the CPU computation performance improvements mean that PHP might now be able to compete in a field it did not compete in before - we can now probably use PHP in areas where we would have had to switch to a different language for decent performance before now. Comments and Feedback welcome on Discourse: PHP 8.0 and 7.4 benchmarks, Ibexa DXP was announced in October 2020. Please enable JavaScript to view the comments powered by Disqus. In the real world YMMV. Upshot: We won't see an immediate improvement of our default use cases, but there are two things I'd like to point out before you go dismissing the JIT out of hand: All in all, enabling JIT does not seem to harm our applications and might even help in high computational load scenarios. I've picked an example that I know speeds up really well when reimplementing it in C. I wrote about this RDP algorithm some time ago.. What it does is to take a line of geospatial points (lon/lat coordinates), and simplifies it. A great start for 8.x. That's not to say that PHP 8.0 is a disappointment by any means. Sidenote: Comparison with PHP 7.4 Regarding performance JIT seems to be a mixed bag here, slowing down at low concurrency and providing a significant improvement to throughput over OPCache Preloading only. This allows you to pass arguments to the function based on the parameter name rather than … Thanks to André Rømcke pointing it out! With the arrival of Composer 2.0 and PHP 8.0 there has been a significant updates to the foundations for Ibexa DXP and numerous other software projects powered by PHP. A total of five configurations were tested using a PHP-FPM and Nginx setup: The OPCache config the same used for the post benchmarking OPCache Preloading: The load balancing was ran using hey and I report the numbers for throughput (req/s) and response time (ms). Php 8.0 vs php 7.4 and php 8.0 features performance and benchmark install and setup guide. PHP 8.0 now ships with a JIT compiler that can increase that performance boost even further. It's been an exciting few months for PHP developers. JIT. Pinterest. JIT is set to increase the speed of an application by the technique used to handle the compilation of the scripts. Performances are a bit increased compared to PHP 7.4: 2.6%. One can clearly see that in web applications the added performance will be barely noticeable. php 8 JIT benchmark. 16 comments ... Preferably it should be PHP 7 vs PHP 8 no JIT vs PHP 8 JIT. PHP 8.0 brings with it many new language features on top of the opt-in JIT compiler support. One of the most important new features in PHP 8.0 is Just-In-Time Compiler.JIT can bring performance improvements by compiling and storing the full or frequently called parts of a PHP application as CPU machine code, and directly execute it, which bypasses the Zend VM and its process overhead. Let's understand how it works all together. Following the work which was done for version 7.0 of PHP and offering significant improvements in it, the performance in PHP 7.1 and PHP 7.2 have been rather modest. Important information : JIT is not activated because we have some issues with it for now. 16 comments ... Preferably it should be PHP 7 vs PHP 8 no JIT vs PHP 8 JIT. This is a quick round of benchmarks done on the latest release of both projects. The Math is 20k requests with 500 connections = 40 requests per connection, if each request does not take longer than 25ms. You'll be better off by upgrading from PHP 7.3 to 7.4 and enabling OPCache Preloading. For throughput there seems to be no change in concurrency 10 to 100, but PHP 8.0 with JIT is curiously less performant as low concurrency but comes alive and edges past 7.4 with OPCache Preloading from at 25+ concurrency onwards.

The OS was Ubuntu 20.20 with PHP installed from the packages from Ondřej Surý. Most importantly is good to see that there have been no performance regressions (like there was with the move from 4.4 to PHP 5.0 way back in 2004). This code is a helper to try out the php with experimental jit support. Only relative performance counts. It's a pure hello world scenario, and should be taken as such.
