[ic] Database design questions

[Bob Puff@NLE]

I have two questions regarding IC's database:

1. Is there any major reason that the default .gdbm files won't work for 
a small to mid-sized site?  It is a performance issue?  When is it 
necessary to use something like MYSQL?

2. I've noticed that in the admin interface of "construct", when you 
delete an order, it really isn't deleted from the transactions database. 
 I would think this file would get to be huge after a while.  Is there 
some sort of auto-pruning that removes the deleted orders?
