Wed May 6 00:41:46 EDT 2009

     [ https://jira.jboss.org/jira/browse/JBMESSAGING-1538?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Clebert Suconic updated JBMESSAGING-1538:
-----------------------------------------

        Summary: Improve Buffer Creation on AIO  (was: Journal Reuse Cache is broken)
    Description: ByteBuffer.allocateDirect is really slow. We should provide an alternative way through our native module.  (was: It was broken after the slicing on ByteBufferBackedBuffer. The native buffer will have a different capacity than expected, making it to throw all buffers away.

Besides, it would be possible to speed up the native buffer creation by doing it directly on the native layer.)
