[jira] [Commented] (SOLR-11200) provide a config to enable disable ConcurrentMergeSchedule.doAutoIOThrottle

    [ https://issues.apache.org/jira/browse/SOLR-11200?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16151822#comment-16151822 ] 

Amrit Sarkar commented on SOLR-11200:
-------------------------------------

Uploaded updated patch with "ioThrottle", that's what CMS is printing in its logs. Though I am not very sure whether we should expose this parameter as the numbers says otherwise.

Merging happens in seperate threads and doesn't interfere with the threads which creates and writes segments. So even if we provide this option to the users, they STRICTLY shouldn't expect much improvement.
