Like I said at the beginning of this post: I want to measure the relative impact the JIT has on real-life web projects. PHP has evolved, and the next major legs are PHP 8.0.0 and the JIT (Just in time) compilation. Start your free 14-day trial today. The JIT compiler is seen as the next major advancement for opening up better performance out of PHP. It was a much bigger leap than the previous PHP versions. We know from the RFC that it does have a significant impact on calculating a fractal. Be aware that these benchmarks don't say anything about whether the JIT is useful or not, they only show whether it can improve the performance of your average web application, or not. PHP 7.3: 131.37 req/s PHP 8.0 + JIT: 133.57 req/s.

Following on from a PHP 8/JIT benchmark on twitter, I decided to have a look myself.. RSS — Performances are a bit increased compared to PHP 7.4: 2.6%. We're also touching several core parts of Laravel as well: routing, the dependency container, as well as the ORM layer. Instead of PHPDoc annotations for a combination of types, you can use native union type declarations that are Patreon — There are some sidenotes to be made about the actual impact on real-life web applications, which is why I ran some benchmarks on how the JIT performs (I've listed all relevant references in the footnotes as well). UPDATE 1: This article was originally missing the numbers with the PHP 8.0 JIT due to it not being enabled by default.Thanks to André Rømcke pointing it out!. Newsletter — Even though most of the fundamentals for JIT-enabling PHP haven't changed - we believe there is a good case today for JIT-enabling PHP.

I'll be running PHP FPM, configured to spawn 20 child processes, and I'll always make sure to only run 20 concurrent requests at once, just to eliminate any extra performance hits on the FPM level. I'm thinking about machine learning, AI, stuff like that. We're going to compare no JIT with the function and tracing JIT; using 100MB of memory. As you can see: a case of the JIT performing worse.

The benchmarks were done on PHP 8.0-RC5 and Symfony 5.2-RC2. Like I wrote before: there's very little hot code to be optimised in real-life applications, we're only rarely doing fractal-like computations. In short, PHP is significantly faster, but for the time being, most of the existing PHP code in the world will not be much faster. For PHP 5 => 7 the Zend/bench.php performance increased 4x!

Tracing JIT, the most promising of the two, shows about 3 times better validated at runtime. The new match is similar to switch and has the following features: Instead of null check conditions, you can now use a chain of calls with the new nullsafe operator.
