[GNC] Any performance improvement in GnuCash 5.x?

[Lipp F.]

I am wondering if users can comment on performance for GnuCash 5.x. I
remember reading that  GnuCash 5.x is supposed to use proper SQL to query
the records and not load the entire history of records in memory on startup.

For the record, I am using pretty new hardware, sqlite database with about
20 years of transactions and GnuCash is not responsive at all. Takes like
tens of seconds for an action to happen after clicking a menu item.

TIA.
