Mark Miller commented on SOLR-7280:
-----------------------------------
bq. // This assumes replicaCount is less than coreLoadThreadCount?
Why is that a question?
If you don't have enough threads to load all the cores in a shard, you have to
wait for the leader vote timeout which is long.
That doesn't seem look good default behavior. How does this address that? I'm
only mildly caught up on the related issue.

> 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.
