The profiling result for loading all these classes with some 25.000 lines of code is: start:00:04:50.999346 stop :00:04:51.432091 The loading takes some 432 Milliseconds that ok for so many classes. Doing the same with 60 classes in real code environment takes from 3 to 25 secs before Apache crashes ... awk ' BEGIN { for (i=1;i<200;i++) { class=sprintf("class%03d",i); fname=class".php"; print "<?php" > fname printf("class %s {\n",class) >>fname printf(" public $somevar;\n") >> fname for (j=1;j<60;j++) { printf(" public function somefunction"j"() {\n") >> fname printf(" }\n") >>fname } printf("} // %s\n",class) >>fname print "?>" >> fname close(fname); } fname="test.php"; print "<?php" > fname print "include(\"profile.php\");" >> fname print "profile(\"start\");" >> fname for (i=1;i<200;i++) { class=sprintf("class%03d",i); classfname=class".php"; printf("require_once(\"%s\");\n",classfname) >> fname } print "displayProfile();" >> fname print "?>" >> fname close(fname); } ' profile.php has the following content: <?php /** * get a Timestamp in string format */ function getTimestamp() { $_time = gettimeofday(); return strftime("%X.", time()).$_time["usec"]; } /** * profile a given step * @param the stepname */ function profile($step) { global $profile_times; $profile_times[$step]=getTimestamp(); } /** * display the profile */ function displayProfile() { profile("stop"); echo "<BR>"; global $profile_times; foreach ($profile_times as $_step=>$_time) { echo $_step.":".$_time."<BR>"; } // foreach } // displayProfile ?> Reproduce code: --------------- It said: Please do not post more than 20 lines of source code. If the code is longer then 20 lines, provide an URL to the source code that will reproduce the bug. Sorry - If I'd provide the URL I'd have to provide a server that may crash any time. A Zip File with the code can be made available by us XPath.Class.php loading took up to 1.9 secs in our enviroment alone when using the __Autoload feature: be/estro/genepi/classUserManager.php:23:42:12.556828 com/bitplan/common/XPath.class.php:23:42:14.405958 Expected result: ---------------- Performance should be acceptable that is class loading should take less than 300 millisecs. Actual result: -------------- Loading of a single class with 5600 lines of code takes 1.9 secs: be/estro/genepi/classSession.php:23:42:12.422696 be/estro/genepi/classUserManager.php:23:42:12.556828 (250 lines of code take approx 130 Millisecs ...) com/bitplan/common/XPath.class.php:23:42:14.405958 5600 lines take 1.9 secs ... ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=27761&edit=1
