It can actually (C++ compilers tend to be MUCH worse than C compilers, especially when it comes to optimizations). We need to see the non thread safe stats though, if the scanner functions take like 1%, it makes no sense. If they take 30%, it's more than reasonable. Zeev -- Zeev Suraski <zeev@zend.com> http://www.zend.com/ For a PGP public key, finger bourbon@netvision.net.ilWe don't really see the performance hit in the stats Thies sent (unless I missed something). Thies - can you send the stats for the thread unsafe version? Well, he said that yy_get_previous_state(), lex_scan() and yy_get_next_buffer() are all taking up more time than zendparse() in ZTS mode while in non-ZTS mode zendparse() is the busiest function. That can't be good and his numbers reflected that. I don't think this can be attributed solely to g++.63% zendFlexLexer::yy_get_previous_state() 12% ZendFlexLexer::lex_scan(...) 7% zendFlexLexer::yy_get_next_buffer(...) 2% zendparse() in "not-ZTS-mode" zendparse is the "busiest" function...
