It still doesn't make sense as it looks like the BundleCache is the gating factor.

So why is it necessary to have this BundleCache?  I tried configuring it and it doesn't pick
up my changes?  Are there alternatives?

Thanks,

is to partition your tree.  I had run into this issue as well a while ago (although I had
only around 10K under a parent node), and took the usual recommendation of partitioning the
tree.  Performance increased drastically after that.
