I still think that's not the case. The array size is large enough to grab all 1597 rows at once. Secondly, I also ran the same SQL code from SQL Developer and didn't witness this kind of lag. Neither did it happen in the legacy script nor in a bare-bone Python script I've made for testing (just displaying fetched rows to console). But thanks anyway. If anyone has other ideas, please let know. - Grzegorz ------------------------------------------------------------------------------ Precog is a next-generation analytics platform capable of advanced analytics on semi-structured data.
