How is the performance of php8?

PHP 8 delivers significant performance gains thanks to the following improvements: Core performance improvements: JIT compiler preloading coroutines Language feature improvements: Union type attributes Other optimizations: OPcache optimized garbage collector improvements Benchmarks reveal PHP 8 has about 20%-30% performance improvement over PHP 7.4.

Performance of PHP 8

The performance of PHP 8 has been significantly improved compared to the previous version , which brings a number of optimization measures and functional enhancements.

Core performance improvements

• JIT compiler:PHP 8 introduces the JIT (Just-In-Time) compiler, which can Dynamically compile PHP code to native code for faster execution.
• Preloading:PHP 8 allows preloading of commonly used classes and functions, thereby reducing load times and improving response times to initial requests.
• Coroutines:PHP 8 introduced coroutines, allowing multiple tasks to be processed simultaneously in one request, improving concurrency and reducing latency.

Language feature improvements

• Union types:PHP 8 adds support for union types, allowing variables to be stored differently type of value, thereby improving code readability and flexibility.
• Properties:PHP 8 introduced properties, allowing properties to be declared and initialized directly in the class definition, reducing boilerplate code and improving code maintainability.

Other optimization measures

• OPcache optimization:PHP 8 optimizes OPcache, a cache of compiled script bytes code components, thus improving script execution speed.
• Garbage collector improvements:PHP 8 improves the garbage collector, reducing memory overhead and improving performance.

Benchmark test results

The benchmark test shows that the performance of PHP 8 has been significantly improved compared to PHP 7.4:

• TechEmpower Framework Benchmark: PHP 8 is about 30% faster than PHP 7.4.
• WordPress Benchmark: PHP 8 is about 20% faster than PHP 7.4.

Conclusion

PHP 8 brings Significant performance improvements. These optimizations make PHP 8 ideal for handling high-load applications and improving web application performance.
