Benedict reassigned CASSANDRA-9240: ----------------------------------- Assignee: Benedict > Performance issue after a restart > --------------------------------- > > Key: CASSANDRA-9240 > URL: https://issues.apache.org/jira/browse/CASSANDRA-9240 > Project: Cassandra > Issue Type: Bug > Reporter: Alan Boudreault > Assignee: Benedict > Fix For: 3.0 > > Attachments: cassandra_2.1-clientrequest-read.log, > cassandra_2.1.4-clientrequest-read.log, cassandra_2.1.4.log, > cassandra_2.1.5-clientrequest-read.log, cassandra_2.1.5.log, > cassandra_2.1.log, cassandra_trunk-clientrequest-read.log, > cassandra_trunk.log, cassandra_trunk_no_restart-clientrequest-read.log, > cassandra_trunk_no_restart.log, issue.yaml, run_issue.sh, trace_query.cql > > > I have noticed a performance issue while I was working on compaction perf > tests for CASSANDRA-7409. The performance for my use case is very bad after a > restart. It is mostly a read performance issue but not strictly. I have > attached my use case (see run_issue.sh and issue.yaml) and all test logs for > 2.1.4, 2.1.5, cassandra-2.1 and trunk. > 2.1.4 and 2.1.5 are OK (although 2.1.4 seems to be better?): ~6-7k ops/second > and ~2-2.5k of read latency. > branch 2.1 and trunk are NOT OK: ~1.5-2k ops/second and 25-30k of read > latency. > branch 2.1 and trunk are OK without a restart: ~ same perf than 2.1.4 and > 2.1.5. > I can help to bisect and/or profile on Monday if needed. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
