Could you try the same operations on COPIES of the databases, on both machines?
An original live DB can be slower than a copy, because of data structure
fragmentation, garbage collections etc. (on the filesystem, but also in tables)

Just a thought about another thing to try, since we have established that
the production hardware is indeed faster.
