PHP 7.4 To PHP 8.6 Benchmarks, PHP 8.6 JIT Performance
Image: phoronix.com

The article presents fresh PHP performance benchmarks from PHP 7.4 to PHP 8.6, including a look at the JIT performance enabled in PHP 8.6. The benchmarks were run on an Intel Xeon 678X system running Fedora 44.

Why it matters

These benchmarks provide insight into the performance of PHP 8.6, which is expected to be released later in the year. The results can help developers and users understand the performance improvements in the latest PHP versions.

Imagine you have a big box of tools, and each tool is a different version of PHP. The article is like a report card for these tools, showing how well they perform compared to each other. The report card shows that the latest tool, PHP 8.6, is doing a good job, but there are some areas where it needs improvement.

Analysis

PHP 8.6 Performance Overview

The article presents a comparison of PHP 7.4 to PHP 8.6 performance, including a look at the JIT performance enabled in PHP 8.6. The benchmarks were run on an Intel Xeon 678X system running Fedora 44.

The results show that PHP 8.6 with the JIT enabled helped out slightly in some benchmarks. However, there was a regression in PHPbench relative to PHP 8.5. The PHP 8.6 performance was looking nice and more incremental gains over PHP 8.5, aside from the PHPbench regression.

PHP 8.6 JIT Performance

The article also looks at the JIT performance enabled in PHP 8.6. The results show that PHP 8.6 with the JIT enabled helped out slightly in some benchmarks. However, the JIT performance was not a significant factor in the overall performance of PHP 8.6.

Conclusion

In conclusion, the article presents a comparison of PHP 7.4 to PHP 8.6 performance, including a look at the JIT performance enabled in PHP 8.6. The results can help developers and users understand the performance improvements in the latest PHP versions.

Key points

  • PHP 7.4 to PHP 8.6 performance benchmarks were run on an Intel Xeon 678X system running Fedora 44.
  • PHP 8.6 with the JIT enabled helped out slightly in some benchmarks.
  • There was a regression in PHPbench relative to PHP 8.5.
  • PHP 8.6 performance was looking nice and more incremental gains over PHP 8.5, aside from the PHPbench regression.
The Upside

If the PHP 8.6 performance continues to improve, it could lead to faster and more efficient web applications. This could be a significant advantage for developers and users who rely on PHP for their projects.

The Downside

However, the regression in PHPbench relative to PHP 8.5 is a concern. If this issue is not addressed, it could lead to slower performance in PHP 8.6 compared to earlier versions.
