See

"If a thread attempts to use the connection while another one is
using it, it will wait until the other thread has finished its
current operation. ...
This is fine for applications and applets but can cause a
performance problem with servlets. With servlets you can have a
heavy load on the connection. If you have several threads
performing queries then each but one will pause, which may not
be what you are after."

I'm not sure what you mean by that. If you create a singleton
I'd say there is exactly one connection.
