Re: PHP profiling results under 2.0.37 Re: Performance of Apache 2.0 Filter

In case it's helpful to the PHP developers, here are some more performance problems that I found by running a quick system call profile of PHP-4.2.1 within Apache-2.0.37-dev: * php_request_shutdown() calls shutdown_memory_manager(), which does a large number of calls to free() per request. If there's any way to get the PHP allocator to use an APR pool, that should help speed things up a lot. (The mallocs and frees are going to be especially problematic within multithreaded MPMs.) * The lex_scan() function consumed a lot of CPU time, even though in my test case (a file with no actual embedded scripting code) only the loop right after the "yy_match" label ever got executed. --Brian
