Art,
I wonder if 1518 is a max block size. Perhaps a large block needs to be
split into manageable chunks.
I've also noticed _a lot of activity_ when accessing a database over
dialup and would be interested to know how to lessen the burden. I got
some improvement by making certain that queries were prepared just once.
(You aren't using TTables, are you?)

Regards,
Aage J.

The "stuttering" of the value 1518 makes me wonder if the BDE (or possibly
gds32) is attempting a query; timing out; and then re-sending. OTOH, the
client doesn't resend. Could the server be looking for an ACK and
re-sending if one doesn't come through?
