Hello, I’ve been doing some tests for uploading large files (say \> 50MB) from a form using ruby on rails, has anyone experienced poor performance during this operation ? I’ve tried every method described in wikis, tutorials, and even a few plugins to do this. In all cases the CPU of my (old) powerbook G4 goes to 100%, and it takes about a minute to upload a 50MB file to localhost, and more than 5 minutes for a 100MB file. I’ve tried the same operation in php and it takes about 15 seconds without occupying all the resources. At first i thought it was a matter of what code i was using to save the file, but in later tests i discovered that the process slows down just during the upload process, even if my controller code is no more than calling the array params[:uploaded\_file], without saving the file anywhere. I don’t know what to think, maybe it is some flaw with WEBrick… I am currently using php to save the file in my application, but I would like to know if there is a “rails way” that you know. thanks in advance, Pier Luigi R. p.s. I’m a newbie, please don’t be rude ---

I didn’t check the CPU usage though. The only problem was memory usage. If I had to put such a thing in production, I won’t use Rails for the upload, there are Mongrel plugins and web server extensions designed to do file upload without monopolizing a Rails process (and bringing its resident memory size through the roof), Google them, IIRC you can find Howtos to integrate them with Rails.
