It matters greatly what software/drivers you are using to connect with. 
You need to first consult the documentation for CoreLab's MySQLDirect for 
details about whether it pools connections or not. The connections are 
pooled client-side, not server-side so I would start with that library.

You may also want to glance through the .NET docs too. I don't know if 
MySQLDirect has it's own objects or if you just use it as you would an 
ODBC driver through the ADO framework.  That could mean that you are 
getting an additional layer of "assistance" from the .NET/ODBC manager 
libraries. That "assistance" may also be pooling connections for you (in 
an attempt to help).

Personally, I have had to sometimes dig very deep to find adequate 
documentation about some of Microsoft's "assistance" features in order to 
figure out how to either turn them on, turn them off,  or learn how to 
live with their unruly behaviors.

Good luck, sorry I wasn't more help...
