PHP 8 introduces two JIT compilation engines. Tracing JIT, the most promising of the two, shows about 3 times better
|

performance on synthetic benchmarks and 1.5–2 times improvement on some specific long-running applications. Typical
|

application performance is on par with PHP 7.4.

<p>
|

PHP 8 introduit deux moteurs de compilation JIT (juste à temps/compilation à la volée).
|

Le Tracing JIT, le plus prometteur des deux, montre environ 3 fois plus de performances sur des benchmarks
|

synthétiques et 1,5-2 fois plus de performances sur certaines applications à longue durée d'exécution.
|

Généralement les performances des applications sont identiques à PHP 7.4.

PHP 8 引入了两个即时编译引擎。

Tracing JIT 在两个中更有潜力，它在综合基准测试中显示了三倍的性能，
