The SQL Server ODBC driver has two driver-specific options for profiling the performance of the driver.
The SQL Server ODBC driver can log performance statistics in file. The log file is a tab-delimited file that can be analyzed in any spreadsheet supporting tab-delimited files, such as Microsoft Excel.
The driver can also log long-running queries (queries that do not get a response from the server in a specified length of time). These queries can later be analyzed by programmers and database administrators.
