Regarding #2, you also need to be aware of how parameters interact with each other. For example in non-direct loads, ROWS and BINDSIZE work hand-in-hand. Increasing one but not the other (or not enough) will bottleneck and it will use a smaller array to load.

Not enough information. Increased from what? To what? If you increase the array size enough to start swapping, it may have a negative impact on performance. ;)
