Date Thu, 07 Feb 2013 07:39:12 GMT

    [ https://issues.apache.org/jira/browse/HAMA-732?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13573276#comment-13573276

Tommaso Teofili commented on HAMA-732:

that could be an interesting idea, maybe better as hama-offheap in case we choose to use not
only DM facilities.

I'll try to do some benchmarks and report here.

> Since Apache DirectMemory can keep objects outside of the java heap that could help on
improving performances.
> I created a simple extension implementation of VerticesInfo which uses Apache DirectMemory
