No. It's as slow as molasses. The standard catalog is not optimized for

No. It will grab fields from multiple product tables without modification, but
so could a single query if it were designed correctly. (Or two queries if the
tables are in different databases.)

The flypage is only one of many poorly-optimized pages of the standard catalog.
The search results and category results are even worse (because the problem is
multiplied by the number of products in the category).
There's really nothing to recommend the current design, maybe someday someone
will get around to fixing it.
