...I'm trying to figure out a way I can show it to you and others -
problem is the codebase is quick large and there is no installer,
no demo database exists etc - its made to be tacked onto
the front of whatever firebird DB.

I will also confess that my code takes a little more hardware
than your to run fast - the amount of abstraction and the complexity
of the DHTML that is output (the generation thereof being completely
generic) is heavy - at one point it was getting _too_ slow and I was
literally forced to dive in a do some major speed optimization...
using the profiler of xdebug1.3 (still can't figure out how to get
xdebug2.0 working) I found (for instance) 40,000 calls to strtolower()
... there are somewhat less now! - one of the pit falls of writing
completely generic code.

If you are interested I will sort out a login on one of my development
boxes/versions - let me know offlist.

what about 'misusing' BLOB filters to record/detect changes? not that I have
ever used BLOB filters but the way I read about them they may well be able to funtion
as pure 'change detectors' given that they seem to be pretty much UDF in so much as
the way you write/implement them ... which makes me wonder if the UDF2PHP hack
that Ard played with is in a usuable state.

I am probably showing my lack of knowledge - I was assuming that
one would give hints to the optimizer as part of the query - made
this is totally wrong - how is it actually done (in general)?

the nice tools I have to work with firebird are obviously keeping me
at arms length for a reason ;-)

btw - pass me _any_ firebird book - there is a shortage of good information
on it!
