#27814 [Asn]: Multiple small packets send for HTTP request

ID: 27814 User updated by: Olaf at XCC dot TMFWeb dot NL Reported By: Olaf at XCC dot TMFWeb dot NL Status: Assigned Bug Type: Performance problem Operating System: Linux, Windows XP, 2003 PHP Version: 5.0 Assigned To: wez New Comment: iliaa, are you talking about ob_start()? I'm not talking about the output traffic between PHP script/server and browser/client, but about the input traffic between script/server and php.net generated by file_get_contents(). Previous Comments: ------------------------------------------------------------------------ [2004-03-31 18:04:36] iliaa@php.net ------------------------------------------------------------------------ [2004-03-31 17:55:02] wez@php.net You're correct; there is no write buffering for the http request. ------------------------------------------------------------------------ [2004-03-31 14:49:43] iliaa@php.net Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php Turn on output buffering. ------------------------------------------------------------------------ [2004-03-31 14:48:37] Olaf at XCC dot TMFWeb dot NL Description: ------------ This code sends two packets, one of 16 bytes and one of 17 bytes. I guess this is caused by multiple calls to php_stream_write in http_fopen_wrapper.c: php_stream_url_wrap_http_ex Preparing the entire request in one buffer and sending it via one call should produce less packets (and be faster). Reproduce code: --------------- <?php echo strlen(file_get_contents("http://php.net/")); ?> Expected result: ---------------- One packet of 33 bytes. Actual result: -------------- Two packets. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=27814&edit=1
