- tiffanyh 10y agoI'm confused, so PHP 7 today does not have a JIT yet its performance is already on-par with HHVM (which has a JIT). Are you then suggesting that PHP 8 (with a JIT) will be significantly faster than HHVM?
- TazeTSchnitzel 10y agoNot necessarily. It may mean that a lot of HHVM's performance improvements were not related to JIT.
- otto_ortega 10y agoI'm also confused. Php 7 has Opcache, which according to the documentation: "OPcache improves PHP performance by storing precompiled script bytecode in shared memory, thereby removing the need for PHP to load and parse scripts on each request." How would JIT features come into play with it?

- TazeTSchnitzel 10y agoPrecompiled here means bytecode, not machine code. OPcache is similar to, say, Python's .pyc files.
