You have hit on a performance anti-pattern. Throwing more threads at an an \
application does not necessarily mean that it will perform better. Eventually, the \
contention for common resources will work against you. For every application there is \
a sweet-spot for the optimal number of threads it can handle (and that includes the \
optimal number of database connections). One of the purposes of performance tuning is \
to find that sweet spot. From what you wrote, I suspect that somewhere around 350 \
connections is the sweet-spot for your app.
