Re: [PHP] move_uploaded_file and CPU wait state (IO)
Hi, I have changed the directory to the same disk. Results are _much_ better! So nothing to blame on PHP, only my lack of knowledge about *nix-like system *blush* Thank all for the advice and help! Cheers, Aleks PS. defining of php_value in virtual host of apache did not work, so I changed php.ini value.

When you move a file between partitions it has to copy the whole file then remove it from the original place when it has verified it has copied ok.

Re: [PHP] move_uploaded_file and CPU wait state (IO)
Hi, Yes, /tmp is on another disk then the final directory. I shall move it to the same disk (tmp_upload_dir) right now. Question: can I define tmp_upload_dir to be otherwise just for one host in apache conf, like: php_ini upload_tmp_dir /some/dir I am not sure that this works for all PHP ini settings? Will let you know how this works out! Thank you! Regards, Aleks PS.

But then again it really doesn't explain the 40+ server load, you may have other issues at hand.

Re: [PHP] move_uploaded_file and CPU wait state (IO)
Are you sure its the move_uploaded_file() function that is causing the delay? It could be the actual upload of the file itself. If it is the function causing the delay than try the rename() function instead. Also, I have used the copy() and unlink() functions and they work fast.

Re: [PHP] move_uploaded_file and CPU wait state (IO)
My first mailing, if I'm in wrong group or such, let me know ;) You've come to the right place :) Here comes my question. I have implemented file uploads to my server. At the end of upload, file is beeing moved from /tmp to permanent directory. However, whenever this happens, CPU goes berzerk and waits for disk to finish moving file. As allowed files may be up to 100 MB per file, having more then 3 users makes complete server freeze. Meantime, server load reaches skyhigh 40+. After file is moved, server resumes normal operation, however while moving file server is completely not responding. Is /tmp on a different disk partition to the final directory ? That could explain it - it's like moving a file on your windows machine from c: to d: Can you move the 'upload_tmp_dir' to a new directory on the same partition as the final directory? See 'upload_tmp_dir' in your php.ini file. Don't change your move_uploaded_file call to use rename() and unlink() - you'll run into problems and it bypasses the checks built into move_uploaded_file. -- Postgresql php tutorials http://www.designmagick.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
