Bug #13094 Updated: Upload very slow

ID: 13094 Updated by: sniper Reported By: mvl@lionsolutions.nl Status: Closed Bug Type: Performance problem Operating System: Windows 2000 PHP Version: 4.0.6 Assigned To: sniper New Comment: This should be fixed in CVS now. You can try the latest development build from http://www.php4win.com/ but make sure it's dated after 27th of October 2001. Also, there are some minor leaks still in the new code. If you encounter such leaks, please send the shortest possible code + html with which you can reproduce the leak to php-dev@lists.php.net (or me) so we can get rid of these leaks. The fix will be in PHP 4.2.0. --Jani Previous Comments: ------------------------------------------------------------------------ [2001-10-28 12:10:12] jeroen@php.net Fixed in CVS by Jani, will be fixed in 4.2.0 ------------------------------------------------------------------------ [2001-09-02 16:52:23] jeroen@php.net Work in progress... ------------------------------------------------------------------------ [2001-09-02 11:57:36] jeroen@php.net This has nothing to do with 2291. The problem probably is that PHP takes all HTTP-post data into it's memory, and only after the complete header (WITH all files) are in-memory, php_mime_split is called to get the files out of the request and save them to disk. So if you need to recieve file-uploads of 100MB or something, PHP needs 100MB of RAM... otherwise it will swap and thus be terribly slow (especially on Windows) A real solution would be to rewrite php_mime_split to run on-the-fly... which at first glance isn't terribly hard. ------------------------------------------------------------------------ [2001-09-02 11:17:11] jeroen@php.net Seems duplicate of 2291, but that one should be fixed in 4.0.6 ------------------------------------------------------------------------ [2001-09-02 07:34:53] mvl@lionsolutions.nl ?php if(is_uploaded_file($userfile)) { $FileNameAdd = $FileName; //Prefix for filename using uniqid(); $FileNameAddDB = $DBFileName; //Including prefix used for database $filename = $HTTP_POST_FILES['userfile']['name']; //Filename as selected by user $FileExt = substr(strrchr($filename, "."), 1); if(array_search($FileExt, $Extensions) == FALSE) { ?> <font class="warning">Not allowed to upload this file.</font> <?php exit(); } $DBFileSize = $HTTP_POST_FILES['userfile']['size']; $DBFileName = $FileNameAddDB.$filename; move_uploaded_file($userfile, $Mapping . $FileNameAdd.$filename); ?> Didn't compile anything just use the compiled version as download from website. When I upload a file bigger than 10 MB, it takes a very long time (if it uploads) I adjusted all the needed variables in php.ini. I'm using it for files (>150MB) over a Lan network. I've tried a ASP uploader and it does the same file in less then three minutes. PHP was working for 30 minutes and still wasn't done. I think this is a bug in the code.
