Jesse,
In case you don't know. HyperCard was written by a genius in assembly
language. Here I'm going to make an assumption (with all of the known
dangers of doing so), Rev was written by a "good" programmer;
probably in a high or higher level language. Big difference. Then Rev
has to do so much more as well.

One huge advantage of using an external databsase like SQLite is the
ability to store data outside of RAM. HyperCard used to use a non-RAM
based design, but Rev stores everything in RAM. So, if you have an
address book which has 100,000 records in a single stack, then all
the
records would need to be stored in RAM simultaneously, creating
performance problems.
Plus, there are a number of huge advantages of using real databases.
Concurrent users, real transaction management, stored procs, etc..
What I can't understand is the given the huge difference in hw
performance since the days of HC, we should at least expect to have
something that performs reasonably well and on par with whatever we
had back then.
But we've gone through all the reasons and I understand, not
posting this to gripe.
