I have a site built in Drupal 7.23, which is supposed to handle large files uploads to it.

I have a node form with 5 File upload fields which is supposed to take 200MB files for each.

What should be the Apache server adjustments that i need to taken in favour of making the upload process seamlessly?

Also i have Video module with FFMPEG configured to convert on cron. Someday I got message form server support team that my FFMPEG is taking 100% CPU.

Also i got some MySQL errors, like Lock TimeOut etc. what to do ?

Please let me know an optimal settings for these kind of server which runs Drupal.

  • taking 100% CPU - are you in shared hosting ?

  • I think you can do it through drupal.org/project/jupload , using this method (not sure) you can upload the files without issue in your server, better see this page( drupal.org/node/1748456 ) , it not mentioned but it processed through ftp so I think it can do the job without affecting the server.

It is normal for the CPU usage to be at 100% when FFMPEG runs. Video compression is a computationally difficult task.

See this related question. If you have a two core VPS then you could make sure that FFMPEG only uses one core and thus always leaves at least one core for Apache/PHP/MySQL.

I created a similar site and it generally worked but it certainly had the occasional errors. It was a 4-core VPS and when transcoding all four cores were often at 100%. If I were to design the site again I think I would use a video transcoding service such as Amazon's Elastic Transcoder. Making sure FFMPEG would recognize all the different file encodings especially MP4 was quite a pain.


You may try File Resumable Upload:

File Resumable Upload aka file_resup adds large files multiple and resumable upload to the File and Image field widgets.


I think you can do it with Remote File Source module without affecting locally.

Remote File Source allows you to add a file from a remote server to a filefield without transferring it locally.

  • I want to add files to the server and convert it into various format so that i can play it in various browsers. Also that is the requirement.
