> Right now our {{DBCPDriverDataSource}} by default sets the {{maxIdle}} to 1. 
> This is not wrong but also not really good in terms of performance.
> It is usually much better to keep it at a much higher number. Usually somewhere around
{{maxActive}}, except when maxActive is really high.
> So I'd rather keep it at 10 or even at maxActive if this param is set.
> If the connections are not used, then they will get unlocked after some time anyway.
> But keeping the number 1 for {{maxIdle}} basically disables the pool, which is not wise.
