Hi Internals,
I would like to start discussion on a Preloadng RFC https://wiki.php.net/rfc/preload
This technology would allow loading some PHP files on server startup and make all the defined classes and functions to be permanently available in the context of future request (without any includes). Despite of performance improvement, this technology is going to be used in conjunction with ext/FFI and JIT.
The implementation is not 100% complete, it misses support for ZTS, because of a error in ZTS interned strings implementation.
I'll try to fix this in nearest week(s).
Definitely cool.
I think it is going to make the file-cache more important as deploy mechanisms are now going to be more likely to do a full cache reset on a deploy so being able to quickly repopulate the shared memory cache from the file cache might help lessen the perf hit of the cache reset.
Yeah. This is a bit unrelated to preloading, but sounds interesting.
Dmitry.
