Mark Miller commented on SOLR-7280:
-----------------------------------
bq. I'll emphasize though that the current code (without this patch) can
prevent a cluster from coming up at all.
The current code is a fix to a bug that existed when we did something like this
before :) I don't want to reintroduce the bug. We didn't, and as far as I know
still don't, support tons of cores very well. As we move to do that, we don't
want to reintroduce bugs though.
> Load cores in sorted order and tweak coreLoadThread counts to improve cluster

> In SOLR-7191, Damien mentioned that by loading solr cores in a sorted order
> and tweaking some of the coreLoadThread counts, he was able to improve the
> stability of a cluster with thousands of collections. We should explore some
> of these changes and fold them into Solr.
