I have a number of servlets (Spring MVC, Rest et...) which all need a database connection
I have a MYSQL database and I use mysql-connector-java-5.1.20-bin.jar to make the connection
The servlets get hit a few hundred times a hour each and I want to improve performance
So how can the current design be improved? (current system is each request into the platform is handled by a servlet which creates a DB connection)
