Before getting too excited about PHP JIT, this year will bring the PHP 7.4 release and there is some speculation that PHP 8.0 will not debut until late 2021. If you want to verify whether the JIT is running, you can use opcache_get_status(), it has a jit entry which lists all relevant information: Here we see the results: enabling the JIT only has a slight improvement. More details as to the state of PHP JIT can be found via this blog post. So let's start with that example.

Nevertheless, JIT could bring several benefits for developers. For PHP 5 => 7 the Zend/bench.php performance increased 4x! If you don’t know what JIT is, it is a compiling strategy in which a program is compiled on the fly into a form that’s usually faster, typically the host CPU’s native instruction set. RSS — First it's best to establish whether the JIT is working properly or not. We're going to compare no JIT with the function and tracing JIT; using 100MB of memory. Like I said at the beginning of this post: I want to measure the relative impact the JIT has on real-life web projects. Or compared to the days of PHP 5.4, PHP 8 with JIT is yielding 5x the performance in this straight-forward PHP benchmark. 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). can troubleshoot fast & get back to coding faster.

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. validated at runtime. Discover how much PHP performance improved from PHP 5 to PHP 7, PHP 7.1 and PHP 8 version with the new JIT engine.Since its creation in 1994 by Rasmus Lerdorf, the PHP language has gone through many improvements.
