## Threading in unixODBC

`unixODBC` uses a strong thread-locking policy that causes big locks with the default configuration for FreeTDS. Performance of multi-threaded applications can be affected because every operation is serialized. To avoid this problem, choose a threading model in `odbcinst.ini`.

Example 5.4. Sample `odbcinst.ini` for threading model

    	[FreeTDS]
    	Driver = /usr/local/freetds/lib/libtdsodbc.so
    	Threading = 1

Example 5.5. Sample `odbc.ini` for threading model

    	[Server1]
    	Driver = FreeTDS
    	Server = myServer1
    	Port = 1433

You can use also a connection string e.g. `DRIVER=FreeTDS;SERVER=myServer1;PORT=1433;`.
