Connection pooling just holds connections to the server.
If a connection is released by the application it is held open and the next connect using the same criteria reuses the connection from the pool. As making a new connection takes a lot of resources then the reuse of the connection will save time.
There will be a timeout after which the connections will be terminated if not reused.

MTS implements connection pooling and so can odbc. Also look at oledb session pooling (not available to VB).
It can have a few effects on spid specific objects though.
see

and

Cursors are useful if you don't know sql.
