Bug #13094 Updated: Upload very slow

ID: 13094 Updated by: jeroen Reported By: mvl@lionsolutions.nl Old Status: Open Status: Analyzed Bug Type: Performance problem Operating System: Windows 2000 PHP Version: 4.0.6 New Comment: 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.

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.
