Subject [jira] [Commented] (SOLR-4074) We should default ramBufferSizeMB to around 100
Date Fri, 16 Nov 2012 22:13:12 GMT

    [ https://issues.apache.org/jira/browse/SOLR-4074?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13499189#comment-13499189

Yonik Seeley commented on SOLR-4074:
------------------------------------

I just committed the change to 100 for Solr to ensure it makes it for 4.1
If Lucene goes to 100 or something smarter like min(100,maxHeapSize/N), we could change the
Solr default to -1 to just pick it up.

> 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.
