> Tested with an oak-snapshot of Monday Feb 24, 10AM EST.
> Noticed that when the amount of nodes indexed - eg wrt a particular property - the adding of nodes becomes slower and slower.
> Will attach a oak-run benchmark to underline this. Basically the scenario where this occurred was:
>  * have a number of "level 1" nodes (eg 100)
>  * under those "level 1" nodes, add a growing list of children, each with a property that is indexed (ie that index is actually growing and is probably causing the slowdown).
