Hi Dominique,

I haven't heard of anyone with that many subcollections before, and I
wouldn't want to hazard a guess about the performance! We would be
interested in hearing about your experiences when your library is
complete, and adding it to this FAQ entry:
http://www.greenstone.org/cgi-bin/library?a=p&p=faqbuild#sizelimit. I
think the critical factor would be merging the results of searching each
collection, and how the performance scales would depend on how this is done.

I'm a little curious why you need so many subcollections. Could you
achieve the functionality you need by combining all the subcollections
into one large collection, and using metadata to maintain the splits?

Regards,

Michael
