I have a client who's selling MP3's on his Mage site. These MP3's are pretty big, around 90MB, and when the download link is click in the account area there can be up to a 2 minute delay before the download actually starts. During the delay, the browser shows "Waiting for www.domain.com...".
I've tried a small file, a couple of kb, and that works quickly, so its obviously something to do with file size.
However, I've replicated the file download outside of Magento and the download starts immediately, even with the 90mb file. Does anyone know what Magento could be doing to cause this delay?
The download script is split between the following 2 files;
I can't see it doing anything out of the ordinary though. Obviously, Magento does A LOT of checks, but those shouldn't change depending on file size.
Bit of a vague one, any help though would be much appreciated.
