1. This is the most horrible method. All users would share the same
connection object, which means, you are going to have multiple threads
trying to use it at once, which means your app will crash instance under any
kind of load.
2. This is slightly better, but still really bad. First off, it means you
have an open connection the entire lifetime of a session. This severely
limits the number of concurrent users, and performs badly.
3. This is how you should handle it. Connections are pooled by default,
opening and closing them is relatively inexpensive. Additionally, you will
get much better performance by not keeping unecessary connections open, 99%
of which time they are not being used.
So yes, #3 is the way to go.
