Subject [jira] [Commented] (SOLR-1575) loading solr.xml takes a lot of time when there are lot of cores
Date Thu, 06 Dec 2012 17:55:09 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1575?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13511561#comment-13511561

Erick Erickson commented on SOLR-1575:
--------------------------------------

Well, first the option is "loadOnStartup", not "loadOnStart". loadOnStart="false" will still
load everything. If you change that and _still_ get extremely long load times, let me know....

Second, I've tested 15K cores parsing on a spinning-disk and it "seemed" acceptable to me
performance wise, 15-20 seconds to get all the files off the disk (but not load cores). 

But real-life tests always trump experiments, please let me know if it continues to not work....

> We have around 38K cores which takes up around 25 mins to start the server. Keep in mind
that no cores are started and this is the time taken for loading the solr.xml.
