So I am sending 300 Update commands to the database. If I use the ProtocolVersion.Ver20 I'm able to send all the commands as 1 string. The command processes in about 50ms vs 300ms if I use ProtocolVersion.Ver30 sending individual PgsqlCommand objects. I'm not concerned with SQL Injection so is using the ProtocolVersion.20 the best way for me to get the best perfomance or does anyone have any other suggestions on how I can improve my performance.
Please use the "UnpreparedExecute=true;" connection string parameter with ProtocolVersion.Ver30 to send all commands with one cmd.ExecuteNonQuery().

The performance of Protocol 3 with "UnpreparedExecute=true;" is approximately the same as the performance of Protocol 2.glavian wrote:does anyone have any other suggestions on how I can improve my performance.
Protocol 2 (or Protocol 3 with "UnpreparedExecute=true;") is better to use if you want to execute many simple commands. But to work with Blob is better (faster) using Protocol 3 with "UnpreparedExecute=false;" (default).
