[jira] [Commented] (SOLR-15096) [REGRESSION] Collection Delete
Performance significantly degraded in 9.0 v 8.8
[ https://issues.apache.org/jira/browse/SOLR-15096?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17269710#comment-17269710 ]
Mike Drob commented on SOLR-15096:
----------------------------------
A single delete collection call ends up causing a lot of exceptions to be thrown (and caught) somewhere. None of this makes it out into our default logs, but it was easy to see in an analyzer. Still trying to understand where the exceptions come from, and if they are indeed the source of the issues here.

> While doing some other performance testing I noticed that collection deletion in 8.8 (RC1) would take approximately 200ms, while the same operation would take 800ms using a recent snapshot ({{a233ed2fd1b}}) from master branch.
> I have not done further investigation at this time.
