@dominikhalvonik JIT performance depends on application. Tracing JIT (1255) should be faster than
function (1205). But you should measure the performance of your app yourself. In case JIT gives less
than 10% improvement (this is very probable), I would disable it at all.
The new version of PHP usually come with new features, fixes and unrelated to JIT performance
improvements. So, for some apps, 8.1 with JIT disabled might be better than 8.0 with tracing JIT.
