This reminds me something I noticed when we migrated from 2.7 to 2.8
Well, it's 2.7 to 2.9 here, but yeah, it's the same big jump ;-)
Our issue was a very big PersistentMapping based tree of objects, which was involved in a lot of RW and RO transactions from different Zope instances (we use ZEO of course). There was no miracle to solve the issue; we had to change the structure to BTree.
How come this wasn't a problem with 2.7? That said, AFAIK, I'm using BTrees everywhere already...
