-------------------------------------------------
Fix Version/s: (was: 2.1 beta2)
> Nodetool Status performance is much slower with VNodes On
> ---------------------------------------------------------
>
> Key: CASSANDRA-7238
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7238
> Project: Cassandra
> Issue Type: Bug
> Components: Tools
> Environment: 1000 M1.Large Ubuntu 12.04
> Reporter: Russell Alexander Spitzer
> Priority: Minor
>
> Nodetool status on a 1000 Node cluster without vnodes returns in several seconds. With vnodes on (256) there are OOM errors with the default XMX of 32. Adjusting the XMX to 128 allows nodetool status to complete but the execution takes roughly 10 minutes.
> Tested
> {code}
> XMX | Status
> 32 | OOM
> 64 | OOM: GC Overhead
> 128 | Finishes in ~10 minutes
> 500 | Finishes in ~10 minutes
> 1000 | Finishes in ~10 minutes
> {code}
