Yes, you experience the same than I do.

Essentially, retrieving the data is what is slow (because JDBC / bug 57872).
Without primary key, LibreOffice retrieves the data only once. With primary
key, LibreOffice trusts it can get the data again and thus caches only a few
dozens of rows. Because LibreOffice fetches the whole data to search (instead
of having the search done by the database, that's bug 44954), search in a JDBC
database (with primary key) is horribly slow.

"Fixing" either of these bugs would make this particular scenario a non-issue.
