made some works since yesterday :
the changes in php.ini are mostly for uploads but also to allow a big script to be executed :
max_execution_time = 60
max_input_time = 60
memory_limit = 51M
post_max_size = 51M
upload_max_filesize = 50M
so now people can upload files until 50MB
also i changed all "getimagesize" in functions.php by "filesize". before i did that when i went into categories with large files it took a long time until the page was showed but with the change it is much faster, sometimes instantly now.
another change that i made was replacing the complete download.php by a script that i found here in the forum which is
http://www.4homepages.de/forum/index.php?action=dlattach;topic=10755.0;attach=334so what happens now when clicking the download button : cpu goes to 100% again and it still needs time until the download window appears, just like if the file needs to be prepared first for download. BUT the download works (even if you have to wait) AND the server is not blocked anymore so that other visitors can still visit the website.
so maybe some one has an issue on resolving the wait and cpu problems?
also is it sure that Jan will make the appropriate changes?
edit : unfortunately while downloading a big file you cannot do anything else as the script doesn't answer anymore for a while.
