Bulk file import in Alfresco

Used the bulk file import, found a bug in the in-place variant, so I had to use the streaming version (copy). But it was not that bad, 1 terabyte in a couple of hours. Well, Alfresco likes a great disk system :)

My recommendations:
  • So don't use In-place before this is fixed: http://code.google.com/p/alfresco-bulk-filesystem-import/issues/detail?id=125
  • Follow the tweaking here: http://wiki.alfresco.com/wiki/Bulk_Importer
  • Do not have the status page open (factor 2-4 slower)!
  • Delete from Alfresco can be slow, so do a test run (need a bulk delete?)
