So, Ronald, are you saying the different approach to meta data transfer is _not_ the issue? > ok, let's figure out what the issue is then. first, let's make sure > it isn't the server that's stalling: configure > log_min_duration_statement with an appropriate value so you start > catching queries that are taking longer then you think the should be. > also some client side logging directly wrapping the SQL invocation > couldn't hurt. is your application jdbc? Ronald said ODBC in his first posting. But since ADS seems to support JDBC as well trying that might be a good test to get another data point. Alternative tools for JDBC tests: http://squirrel-sql.sourceforge.net/ http://www.oracle.com/technetwork/developer-tools/sql-developer/overview/index.html Using the PG client remotely with "\timing on" might be an even better idea.
