Subject [jira] Commented: (LUCENE-2825) FSDirectory.open should return MMap on 64-bit Solaris
Date Mon, 20 Dec 2010 12:45:00 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2825?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12973181#action_12973181

Uwe Schindler commented on LUCENE-2825:
---------------------------------------

Is it slower on Linux-64 because you only enable for windows-64 and solaris-64?

In general I expected that it is faster on all all 64 bit systems.
