Does anybody know why, while building a form which includes ctree database
(implemented via ODBC driver) is incredibely slow during its scroll from the
first to the
last record.I compared it against DBF file even with more records and it
seems
all right. Of course I have got appropriate indices put on ctree database
etc.
Ctree behaves as it had not had any indices whatsoever.
Can anybody help, please ?
Sincerely
Jacek

It probably has to do with the fact that ODBC is generally slow, and
it could also be that the ODBC driver you are using is not
particularly fast (or it's poorly written or both).
