It isn't either-or.  It is the processing of millions of rows over the large in-list which is taking the time. Processing an in-list as a hash table would be great, but no one has gotten around to it implementing it yet.  Maybe Dmitry will be the one to do that.

Yes, it is probably too complex for a novice.  On the other hand, you might not be a novice anymore once you complete it!

Cheers,
