Hello,

Is there anyone tried the JIT compiler with PHP 8.x or made a benchmark?

Someone said it would make your site load faster by 5-8%.

Thanks

JIT compiler or benchmark for PHP 8.x

PHP 8.x introduced the Just-In-Time (JIT) compiler, which is an important feature to speed up the execution of PHP scripts. The JIT compiler achieves performance enhancements by compiling PHP bytecode into machine code. The JIT compiler has been included since PHP 8.0 and has been continuously optimized in subsequent versions.

Importance of benchmarks

Benchmarks are a key way to measure the performance of the JIT compiler. It can help developers understand the specific impact of the JIT compiler on the execution speed of PHP scripts and evaluate the degree of performance improvement.

Official benchmarks

The JIT compiler of PHP 8.x has been officially benchmarked. These tests cover a variety of workloads, such as web applications, database operations, mathematical calculations, etc., to comprehensively evaluate the performance of the JIT compiler.

Benchmarking on your own

If you want to benchmark on your own, you can follow these steps:

  1. Install PHP: Make sure you have installed a version of PHP 8.x that supports the JIT compiler.

  2. Choose a benchmarking tool: Leverage an existing PHP benchmarking tool, such as PHPBench, or write your own script to test specific functionality.

  3. Write a test script: Create a PHP script to test the performance aspects you care about, such as array handling, function calls, database access, etc.

  4. Run the benchmark: Execute the benchmark in a consistent hardware and software environment to ensure consistent results.

  5. Analyze the results: Compare the performance differences when the JIT compiler is enabled and when it is not enabled.

  6. Consider external factors: Include external factors that may affect performance in the test, such as CPU usage, memory conditions, and other services.

Note: Performance test results may vary depending on workload, server configuration, and PHP version. When benchmarking, it is recommended to run multiple times and average to get reliable data.
