Yes, that?s what I meant.

Yes I am familiar with it, I was just trying to avoid it for simple tasks, like
getting a list of all invoices for a customer.  Yes this can take 6+ seconds to
get.

The problem is we are using an application that is 20+ years old, and was never
intended to be accessed via and ODBC driver (luckily we found one, it may be
buggy but it works).  Some parts of the company need to use the original
application, other parts we access through our own data-access system (similar
to AR but simpler).  We currently have an internal web-application that piggy
backs on to the original DB, but need to change some significant things (will
add new tables), and the future plans are to rewrite it so it no longer uses the
original DB.  This would be done subsection by subsection and converted to
Rails, so we are starting now.  We have all of the data access working fine, its
just some transactions are slow for a subset of the data being accessed.

The database itself is non transactional file based system.  The app is written
in Dataflex which is/was a sort of 4GL RAD builder that had its own DB built in.

Very nice.

Yes, there is a 2.2.2 binary build for win32 up on the Apache web site.
