having to grow the file as you do the conversion. Try pumping the
FB database tables with 3-500k junk records, then delete them all. Firebird
shrink the gdb file, so there will be a lot of unused space in the gdb file
to put the converted records into. Then try
the conversion again - I bet it'll be much faster. If that's the case, and
will be doing the final conversion on the customer's site, then just take
pre-bloated .gdb with you on a cd and do the conversion into that.
