[jira] [Updated] (CASSANDRA-3389) Evaluate CSLM alternatives for improved cache or GC performance

     [ https://issues.apache.org/jira/browse/CASSANDRA-3389?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Brandon Williams updated CASSANDRA-3389:
----------------------------------------

    Attachment: 0001-Switch-CSLM-to-SnapTree.patch
                0001-Replace-CSLM-with-ConcurrentSkipTreeMap.patch

'naive' patches (in that all I did was swap out CSLM) for lockfreeskiptree and snaptree.  I didn't see any low hanging fruit improvement.

> Ben Manes commented on http://www.datastax.com/dev/blog/whats-new-in-cassandra-1-0-performance that it's worth evaluating https://github.com/mspiegel/lockfreeskiptree and https://github.com/nbronson/snaptree as CSLM replacements.
