You didn't understand me (my english isn't perfect and there are lacks in vocabulary). PHP uses almost only per-thread resources - global, but only for thread resources. It doesn't use process-global resources (I found only compiled regex cache) so it doesn't need to synchronize on them. There are no lock-contention problems in PHP. > I'm not sure how __thread works but the TSRM implementation already uses > thread local storage to cache the per-thread objects. Not sure __thread > doesn't do the same. as Sascha said - NPTL is the future for multi-threaded applications - I think there is a need for review of TSRM.
