investigate, might be a simple one to fix).

> When investigating DERBY-3312 I found out that performance with the embedded
> driver has decreased a lot as well.
> Analysis on trunk indicate excessive memory usage, causing high allocation
> and garbage collection costs.
> I believe there was another major performance problem in 10.3, but it appears
> fixed in trunk. I have not spent time identifying this problem.
