ive used the semaphores; theyre not too bad (but there are some gotchas) and theyre way faster than file locking. but anyway, regarding the shared memory stuff, youd probly better spend your time working with an opcode caches 'user cache'. i know apc and eaccelerator both provide these mechanisms which is likely very similar to the sysv shared mem. one thing i discovered, playing around w/ the sysv shared mem is the interface kinda sucks... everything must be accessed by a unique integer, whereas (at least in apc [and likely eaccelerator]) you can supply strings as the cache keys. -nathan
