[Zenoss-dev] DB connection pooling testing

[Marc Irlandez]

Devs,

I've uploaded a changeset to the trunk that includes a performance  
optimization...MySql DB connection pooling.

Basically, a single synchronized pool (using Queue) of connections is  
created holding 0 to n DB connections. They are created when needed  
and placed into the pool when you are done using them, thus avoiding  
the open and closing of connections for any event related call.

Since this change touches a bunch of files and affects a pretty big  
piece of functionality, it would be good if everyone downloaded it  
and tested.

Let me know if you feel a difference.

Marc
