Hi All, I have noticed a concerning memory issue when I use the File Upload 1.1 with the following code:
int maxFileSize = 100000; DiskFileItemFactory factory = new DiskFileItemFactory(); factory.setSizeThreshold(maxFileSize); ServletFileUpload upload = new ServletFileUpload(factory); upload.setSizeMax(maxFileSize); List items = upload.parseRequest(request); I set the max file size and the threshold size to be the same (100k) so that files are never writen into the temp directory. The problem I noticed is that when I submitted a form containing 50 input fields, a temporary byte array of 100k was created for each of the 50 fields. So in my case, 50 fields * 100k per field = 5MB of memory was used for a single form being submitted. Is this the normal behavior? Also, the documentation states: # Uploaded items should be retained in memory as long as they are reasonably small. # Larger items should be written to a temporary file on disk. # Very large upload requests should not be permitted. Although I would imagine that "reasonably small" and "larger items" and "very large" would depend on the application, the memory available and the amount of concurrent users, are there any guidelines?
