What are the operations you find are slower ? Can you provide a precise
description (with time) on both servers ?

Actually, the file system hasn't changed, we just have set up
transaction across B-trees, which means updates are either committed
globally, or rollbacked. In M24 and previous versions, transaction was
B-tree based, which means you may end with some dandling references in
some corner cases.

By all means, as transactions are handled in memory, we found that
additions are currently faster thant it was, search should be as fast
(or slow ;-) as it was before.

I'll be interested to know more !
