PHP 8.0 JIT Is Offering Very Compelling Performance Ahead Of Its Alpha

With the venerable PHPbench, going from PHP 7.4 stable to PHP 8.0 Git meant a 7% increase in performance. Not bad, but when enabling JIT that difference increased to 92% over the current stable PHP release! Or compared to the days of PHP 5.4, PHP 8 with JIT is yielding 5x the performance in this straight-forward PHP benchmark.

With some of PHP's own built-in tests, the impact of PHP 8.0 out-of-the-box performance sees a slight improvement over the already fast PHP 7.4 but enabling the JIT support is turning to be quite a performance win.
