     [ https://issues.apache.org/jira/browse/CASSANDRA-668?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jonathan Ellis resolved CASSANDRA-668.
--------------------------------------

       Resolution: Fixed
    Fix Version/s:     (was: 0.9)
                   0.5

(actually I think the best thing to do is tag this 0.5 and resolve it, and create a new issue for further investigation)

> on a heavily loaded system (deliberately exacerbated by running the bonnie++ i/o benchmarking tool at the same time as cassandra -- which might not be too far off from the environment you would see on some VPS hosts), we're seeing CL sync times of 1-5s, causing write pauses.
