Hi everyone, I have 2 questions: The lab that I work for will routinely have to upload files via HTTP of between 2MB and 40MB. We will be saving these as External files but this is not the problem. We can upload 2MB files pretty quickly (~3 seconds), but trying to upload an 8MB file takes about 50 seconds. This is true no matter whether I upload the file as an external one or just as a regular File. Therefore I am guessing that the problem comes from Zope's handling of large files and the definite probability that it is loading the file into memory first before saving it. I have seen other people who have had similar problems: http://lists.zope.org/pipermail/zope/2001-July/094581.html http://lists.ozzope.org/pipermail/ozzope/2001-October/000116.html but there don't seem to be any solutions posted. Is there any way of streaming the file into Zope? My second problem comes with the file once it is uploaded - I know that Zope adds a couple of extra properties to an uploaded file, but is there any way I can get at the original file - maybe removing the properties so that I can pass it into another program for processing?
