Default value of fetch size in oracle command

Hi All,

As part of performance improvement, We are just validating our screens having 200 concurrent users and we face some slowness in some of the screens. We thought some problem with the fetch size property of oracle command.We are using enterprise library. Below code is correct or still we need to increase the size.DO we need to put any rowsize here ? please advice.

OracleCommand Oracommand = (OracleCommand)command;

Oracommand.FetchSize = Oracommand.FetchSize * 8;

IDataReader reader = Oracommand.ExecuteReader(cmdBehavior);

MSVISUAL STUDIO 2010, .net 4.0, IIS7.0, Enterpriselibrary.

Thanks

Deepan.
