ID: 52522 Updated by: paj...@php.net Reported by: roman dot neuhauser at ge dot com Summary: php_curl.dll, php_http.dll take 300ms to initialize Status: Assigned Type: Bug Package: cURL related Operating System: Windows PHP Version: 5.3.3 Assigned To: pajoye Block user comment: N New Comment: Duplicate of #50410 Previous Comments: ------------------------------------------------------------------------ [2010-08-03 13:03:34] roman dot neuhauser at ge dot com Description: ------------ both php_curl.dll and php_http.dll (linked with libcurl) are really slow to initialize. on a machine where `php -n /dev/null` or `php -n -m` takes ~70ms to complete, `php -n -d extension_dir=/... -d extension=php_curl.dll /dev/null` (or php_http.dll) uses above 300ms. seen this on multiple hosts ranging from xp sp2 to server 2003 r2 sp2. 5.2 is not affected which makes me believe it is related to the pooling functionality added in 5.3. Test script: --------------- run this with native PHP in the MSYS shell: : ${PHP53:=/c/Webserver/Apache2.2/php-5.3} : ${PHP52:=/c/Webserver/Apache2.2/php-5.2} for p in $PHP53 $PHP52; do for d in '' php_curl.dll php_http.dll; do echo ${p##*/} using ${d:-nothing} time $p/php -n -d extension_dir=$p/ext/ ${d:+-d extension=}$d /dev/null done done Expected result: ---------------- php_curl.dll / php_http.dll should add at max 100ms each, or at least the documentation should mention prominently the consequences of loading these libraries. i've read pecl_http's and php_curl's documentation, and found no mention of a way to disable the time-consuming functionality. Actual result: -------------- php-5.3 using nothing real 0m0.078s user 0m0.015s sys 0m0.016s php-5.3 using -d extension=php_curl.dll real 0m0.500s user 0m0.000s sys 0m0.015s php-5.3 using -d extension=php_http.dll real 0m0.516s user 0m0.000s sys 0m0.015s php-5.2 using nothing real 0m0.078s user 0m0.015s sys 0m0.000s php-5.2 using -d extension=php_curl.dll real 0m0.172s user 0m0.000s sys 0m0.015s php-5.2 using -d extension=php_http.dll real 0m0.078s user 0m0.000s sys 0m0.015s ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52522&edit=1
