quantify tells me that the c++ parser eats most of the time. (% of .root.) 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... are flex-generated c++ lexers known to be *SLOW* or am i doing something wrong?

It could be that the C++ compiler is much less efficient and doesn't know how to optimize very well. On a busy site, this can become negligible with the persistent registry. Zeev -- Zeev Suraski <zeev@zend.com> http://www.zend.com/ For a PGP public key, finger bourbon@netvision.net.il
