[EP-tech] Sword 2.0 API upload times


CAUTION: This e-mail originated outside the University of Southampton.

Dear all,

 

since very recently, one faculty of our university deposits its dissertations via Sword 2.0 API. The EP3XML with embedded PDF is deposited.

 

Everything works fine, however, the faculty observes that it takes unproportionally long the bigger the size of the PDF is, until they get process termination feedback:

 

  • 3.8 MB: 7 seconds
  • 16.5MB: 2min 30s
  • 22.6MB: 4min

 

Is such a behaviour known to you? Any adjusting screws?

 

We do some checks such as scanning for viruses or format determination using Droid. The former is done immediately in the document_validate.pl, the latter is being triggered after the document has been uploaded. So I don’t see any bottleneck in these processes.

 

Kind regards,

 

Martin
