Ah, but if it is for performance reasons, there is very little to be gained. The big win with APC comes from eliminating disk activity by pointing the executor directly at the op_array along with the in-memory function and class caches stored in shared memory. Restoring these from disk and sorting out where things go in memory is not going to be any quicker than simply recompiling the file. If we had a better opcode structure it theoretically could be faster, but as it is it would take a lot of work to get very small gains. -Rasmus -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
