David Smiley commented on SOLR-7280:
------------------------------------
This is an old issue but nonetheless I want to bring to attention that the
CoreSorter introduced here isn't doing its job. It only does so in its unit
test but not in real-world usage (actual use inside CoreContainer). See
SOLR-14342.

> 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.
