Subject [jira] [Commented] (SOLR-4074) We should default ramBufferSizeMB to around 100
Date Wed, 14 Nov 2012 17:54:12 GMT

    [ https://issues.apache.org/jira/browse/SOLR-4074?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13497279#comment-13497279

Michael McCandless commented on SOLR-4074:
------------------------------------------

I don't think we should increase Lucene's default?  I think apps that care greatly about indexing
performance can tune it upwards ...

> You get diminishing returns after 100, but gains up to 100. In this day and age of RAM,
it seems better to default to 100 and have essentially the top indexing speed the buffer can
give us.
