Dear list, I'm testing an upgrade of a DSpace 5.8 instance to DSpace 6.3 and one of the first things I notice is that Discovery indexing is about three or four times slower than it was before. On the same hardware, my repository with ~85,000 items takes 30 minutes to index with DSpace 5 and three hours with DSpace 6.3 and DSpace 6.4-SNAPSHOT. My development environment is on Linux with a fast SSD and lots of RAM, so I fear it will be even worse on our production server.
I have read that the new Hibernate database layer in DSpace 6 involves much more complicated or time-consuming database queries. How are other people handling this? We're using PostgreSQL 9.6. Could it be time to move to something higher to hopefully gain something from PostgreSQL's own advances?
