>My question is how are you accomplishing the connection pooling?
I have programmed a connection pool in Java - I am sure something similar is possible in most other languages.
Very basically, the concept is as follows:
> Application initialisation
>>> 1) Create X number of connections to the database
>>> 2) Store connections in an Object
>>> 3) Create an array of free and busy connections - put all new connections in free connection array
>>> 4) Object is visible to all components of web application
> Request for a connection
>>> 4) Code asks for a connection from the pool object (3).
>>> 5) Pool object moves connection from free array, to the busy array.
>>> 5) Connection is used to do queries
>>> 6) Connection is sent back to pool object (3).
>>> 7) Pool object moves the connection from the busy array, back to the free array
I hope that helps!
