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. -Rasmus
