Ryan McGuire commented on CASSANDRA-4338: ----------------------------------------- And I notice that the marcuse/4338 line still doesn't have latency metrics, if you'd like me to re-run for those stats, I can. Just need to rebase off of CASSANDRA-6153 (or rewrite my tool to use a known good cassandra-stress; right now it just takes the one from the same branch it's testing.) > Experiment with direct buffer in SequentialWriter > ------------------------------------------------- > > Key: CASSANDRA-4338 > URL: https://issues.apache.org/jira/browse/CASSANDRA-4338 > Project: Cassandra > Issue Type: Improvement > Components: Core > Reporter: Jonathan Ellis > Assignee: Marcus Eriksson > Priority: Minor > Labels: performance > Fix For: 2.1 > > Attachments: 4338.benchmark.png, 4338-gc.tar.gz, gc-4338-patched.png, > gc-trunk-me.png, gc-trunk.png, gc-with-patch-me.png > > > Using a direct buffer instead of a heap-based byte[] should let us avoid a > copy into native memory when we flush the buffer. -- This message was sent by Atlassian JIRA (v6.1#6144)
