I had to restore to the version before the upgrade because the speed was unacceptable. I performed the upgrade again and had the same result. So I restored the before the upgrade again. I checked with the hosting provider, there is apparantly nothing on their side that could be causing it. It must be something with the database. Maybe it has to do with the 'Deleting old default messages' processing taking so long? What are these messages anyway? Do I need to perform any maintenance on the database?
Thanks, Andi
Old Mediaiki versions created the default messages on the Mediawiki: namespace. This is no longer a good idea, and upgrade now deletes those never modified. Skipping that phase on the upgrade wouldn't do any harm (but you may get outdated messages).
