> Key: CASSANDRA-1453
> URL: https://issues.apache.org/jira/browse/CASSANDRA-1453
> Project: Cassandra
> Issue Type: New Feature
> Components: Tools
> Reporter: Jonathan Ellis
> Assignee: Pavel Yaskevich
> Priority: Minor
> Fix For: 0.7.1
>
> Attachments: stress-v2.patch, stress.patch
>
>
> stress.py seems to scale poorly past a fairly small number of
> threads/processes. (against a 3-node, RF=1 cluster, I got 3x as much
> throughput with 4 machines running stress.py -t 32, as running 1 with -t 128.
> these were 8-core client machines, and -t 128 reported only 50% cpu used.)
> since we ship with the thrift java api pre-built, this would also mean not
> making people build thrift before using the stress test, which is at best a
> pain for newcomers and on Windows a major hurdle.
